Reading is an important skill for developing second language competence. The success of a learning a second language is by taking the power of reading. In the classroom, we will face many techniques applied to the students under the expectation that they are able to or easy to understand the lesson. For a teacher, it is necessary to find new teaching media to overcome the problems and not to forget to motivate the students. In this paper, the writer wants to know the effect of picture as a media to improve students’ reading comprehension. The purpose of this research is to find out whether the use of pictures can improve students’ reading comprehension or not. To make the students easily understand about the reading material, teacher needs to have a teaching media. Then, the writer chooses visual media that is picture to increase students’ reading mastery. Pictures are considered as the best media in teaching reading because using picture as a teaching media are able to give the students a clear illustration regarding the correlated topics in texts, tell the students what is going on, and what are the persons in the text are talking about. Nowadays, the pictures and the technologies are becoming more and more advanced. In this decade, we can already materialize a more advanced picture that added by motion and sounds by using simple applications provided in home personal computer. Moreover, the students now are quite used and interested to apply any high tech media.
Based on the result of discussion, it can be concluded that pictures are theoretically can be a good media to help the students enhancing their reading comprehension. Therefore in this view, it is justifiable to hypothetically conclude that using pictures for strengthening students’ visual sense can help them to understand a text.

A method is presented for three-dimensional motion posture correction employing Fuzzy kernel estimation and affine transformation. As selecting human moving node by a visual sensor and smoothing single frame image with irregular motion, noise interference is reduced. Based on principles of perspective and affine transformation, adjustment strategy of three-dimensional posture is deduced for irregular single-frame motion picture. In addition to determination of motion picture rotation, accurate correction of irregular single-frame motion picture is proposed. Experimental results show that, under different noise conditions, the algorithm corrects posture of a three-dimensional moving image accurately and presents strong anti-noise performance.

Full textAbstract:
Methods of assessing presence, a sense of ‘being there’ within a displayed virtual environment, include post-test subjective measures, discrimination tests, and monitoring reflexive responses. Each is limited—either they do not provide a measure of temporal variation, are not feasible with current display technology or are overly content-specific. A measure of presence derived from the method of continuous evaluation (ITU-R, Recommendation BT.500-7, revised, “Methodology for the subjective assessment of the quality of television pictures”, 1995) has been used to overcome these limitations. The results of two experiments are presented. Those of the first experiment established that the methodology is usable under the optimal viewing conditions for the 20 inch stereoscopic TV display upon which our stimuli were presented. It compares within-subject variation on continuous TV picture quality ratings under two viewing conditions—at six picture heights in the light (standard for quality evaluations) and at two picture heights in the dark (optimal stereo TV viewing). The second experiment investigated the effects of manipulations of the visual parameters of stereo, scene motion, and observer-based motion on participants' presence evaluations within edited sections of a stereoscopic film. The results provide support for theories predicting that the extent of sensory information available to a participant is one of the factors determining presence.

Full textAbstract:
Feynman stated that the double-slit experiment “…has in it the heart of quantum mechanics. In reality, it contains the only mystery” and that “nobody can give you a deeper explanation of this phenomenon than I have given; that is, a description of it” [Feynman R, Leighton R, Sands M (1965) The Feynman Lectures on Physics]. We rise to the challenge with an alternative to the wave function-centered interpretations: instead of a quantum wave passing through both slits, we have a localized particle with nonlocal interactions with the other slit. Key to this explanation is dynamical nonlocality, which naturally appears in the Heisenberg picture as nonlocal equations of motion. This insight led us to develop an approach to quantum mechanics which relies on pre- and postselection, weak measurements, deterministic, and modular variables. We consider those properties of a single particle that are deterministic to be primal. The Heisenberg picture allows us to specify the most complete enumeration of such deterministic properties in contrast to the Schrödinger wave function, which remains an ensemble property. We exercise this approach by analyzing a version of the double-slit experiment augmented with postselection, showing that only it and not the wave function approach can be accommodated within a time-symmetric interpretation, where interference appears even when the particle is localized. Although the Heisenberg and Schrödinger pictures are equivalent formulations, nevertheless, the framework presented here has led to insights, intuitions, and experiments that were missed from the old perspective.

This article is an attempt to reflect on Poles' attitude towards the Russian language. Its aim is to reconstruct various “Polish views of Russian” in their objective dimension (with no intention to evaluate or criticise). Three stereotypical pictures of the Russian language present in the Polish common consciousness recreated by the author are based on range of language material. The description of “the three pictures of Russian in the Polish head” (“Polish common knowledge about Russian”) indicates the instrumentality of this language, which occurs in three hypostases. For the first image it is the usual instrumentality of communication (rossicum is an addition and an excess of information within a Polish text), for the second image the instrumentality acquires unambiguously pragmatic features and the rossicum becomes an instrument of effective action, and for the third picture the instrumentality of Russian elements sets in motion the symbolic-cognitive (creating a sense) function of Russian in Polish text.

Full textAbstract:
Although local Hamiltonians exhibit local time dynamics, this locality is not explicit in the Schrödinger picture in the sense that the wavefunction amplitudes do not obey a local equation of motion. We show that geometric locality can be achieved explicitly in the equations of motion by "gauging" the global unitary invariance of quantum mechanics into a local gauge invariance. That is, expectation values ⟨ψ|A|ψ⟩ are invariant under a global unitary transformation acting on the wavefunction |ψ⟩→U|ψ⟩ and operators A→UAU†, and we show that it is possible to gauge this global invariance into a local gauge invariance. To do this, we replace the wavefunction with a collection of local wavefunctions |ψJ⟩, one for each patch of space J. The collection of spatial patches is chosen to cover the space; e.g. we could choose the patches to be single qubits or nearest-neighbor sites on a lattice. Local wavefunctions associated with neighboring pairs of spatial patches I and J are related to each other by dynamical unitary transformations UIJ. The local wavefunctions are local in the sense that their dynamics are local. That is, the equations of motion for the local wavefunctions |ψJ⟩ and connections UIJ are explicitly local in space and only depend on nearby Hamiltonian terms. (The local wavefunctions are many-body wavefunctions and have the same Hilbert space dimension as the usual wavefunction.) We call this picture of quantum dynamics the gauge picture since it exhibits a local gauge invariance. The local dynamics of a single spatial patch is related to the interaction picture, where the interaction Hamiltonian consists of only nearby Hamiltonian terms. We can also generalize the explicit locality to include locality in local charge and energy densities.

Full textAbstract:
A camera sensor may be a useful tool for a number of robotic and autonomous systems when used with MATLAB Simulink for obstacle avoidance. Using a camera sensor and MATLAB Simulink's optical flow algorithm, the obstacle avoidance system is shown in this work. For the purpose of identifying and following the motion of objects in the picture, the system analyses visual data from the camera. The motion vectors of the objects are computed using the optical flow technique, and the robot and obstacles' relative motion is calculated using those motion vectors. In order to provide safe and easy navigation, the system can recognise and avoid obstacles in real-time. The system is easily adjustable and adaptable to diverse applications thanks to the usage of MATLAB Simulink, which enables the integration of several sensor and control systems. The suggested system's findings demonstrate that using a camera sensor with the optical flow algorithm may be a useful tool for obstacle avoidance in a range of robotic and autonomous systems.

Full textAbstract:
Storytelling is one of the most important learning activities for children since reading aloud from a picture book stimulates children’s curiosity, emotional development, and imagination. For effective education, the procedures for storytelling activities need to be improved according to the children’s level of curiosity. However, young children are not able to complete questionnaires, making it difficult to analyze their level of interest. This paper proposes a method to estimate children’s curiosity in picture book reading activities at five levels by recognizing children’s behavior using acceleration and angular velocity sensors placed on their heads. We investigated the relationship between children’s behaviors and their levels of curiosity, listed all observed behaviors, and clarified the behavior for estimating curiosity. Furthermore, we conducted experiments using motion sensors to estimate these behaviors and confirmed that the accuracy of estimating curiosity from sensor data is approximately 72%.

People are increasingly interested in moving object detection technology as a part of computer vision technology, which has grown in importance in recent years. Moving target detection technology is widely employed in military defense, security monitoring, medical examinations, intelligent transportation, and many other industries at the present time. A moving target detection system relies on rapid and accurate video picture segmentation to identify, locate, and analyze the target. The trajectory of a basketball player’s shooting motion and the extraction of features are important to increase the accuracy of basketball players’ shots. This study proposes an area growth algorithm-based approach to tracing the shooting motion of basketball players. The trajectory of the shot motion is captured using a video sensor image tracking approach. The corner points and the edge contours of the trajectory image are extracted using the edge contour feature extraction method, the feature extraction from the firing motion trajectory image is merged with the regional linear growth approach, and the corner points are then marked. Feature extraction improves basketball players’ shooting accuracy and trajectory control ability. Simulation results show that the prediction accuracy of basketball players’ shooting trajectories using this method can reach up to 100%, which improves the accuracy of motion trajectory extraction and enhances basketball players’ shooting motion control.

Full textAbstract:
In this paper, different aspects of the concept of spin are studied. The most well-established one is, of course, the quantum mechanical aspect: spin is a broken symmetry in the sense that the solutions of the Dirac equation tend to have directional properties that cannot be seen in the equation itself. It has been clear since the early days of quantum mechanics that this has something to do with the indefinite metric in Lorentz geometry, but the mechanism behind this connection is elusive. Although spin is not the same as rotation in the usual sense, there must certainly be a close relationship between these concepts. And, a possible way to investigate this connection is to instead start from the underlying geometry in general relativity. Is there a reason why rotating motion in Lorentz geometry should be more natural than non-rotating motion? In a certain sense, the answer turns out to be yes. But, it is by no means easy to see what this should correspond to in the usual quantum mechanical picture. On the other hand, it seems very unlikely that the similarities should be just coincidental. The interpretation of the author is that this can be a golden opportunity to investigate the interplay between these two theories.

Full textAbstract:
In this paper we discuss ways in which the concept that, for want of a better word, we may describe as ‘overness’ is coded in motion predications in English and French. The concept of ‘overness’ is a relational one, the basic spatial sense of which involves some sort of (elongated) superiority of a Figure (a Trajector in the terminology employed by cognitive linguists) vis-à-vis a Ground. This study compares codings in English and French of this concept as it is instantiated in translations of the same original Norwegian texts. The data for the study are taken from the Oslo Multilingual Corpus. Tokens coding motion events are analysed in detail in terms of the coding of Manner, Path, Site and Ground. The results of the study point to substantial differences between English and French in their codings of motion events, with English conforming by and large to the satellite-framed language type. The results for French are much less clear, with the picture resembling more a sort of typological hybrid than a rigid path-framed type.

<p>The "Smart Glasses" are made to make it easier for blind persons to read and decipher written English-language content. A blind people find it exceedingly challenging to travel alone, and they run the danger of getting lost and regular sticks won't allow the person to go around independently in public without things growing worse. The objective of our work is to help blind people communicate more easily by developing a smart assistive glasses using artificial intelligence. The function of the glasses is to read out any text picture as audio text, which can then be heard through a headset attached to the spectacles. OpenCV, optical character recognition and efficient and accurate scene text (EAST) detector were used to identify the text in the image; ultrasonic sensor in the glasses is used to calculate the distance to snap a clear picture. The motion sensor directs the blind to the lecture halls, classrooms, and laboratory locations using an radio frequency identification reader. The results shows that combination of optical character recognizer and EAST detector produced a fairly accurate result, demonstrating the potential of the glasses to recognize the text. Currently, the language supported by the glasses is English, and the distance covered is 40 to 150 cm.</p>

We present an interactive system using one RGB-D sensor, which allows a user to use bare hands to perform sand drawing. Our system supports the common sand drawing functions, such as sand erosion, sand spilling, and sand leaking. To use hands to manipulate the virtual sand, we design four key hand gestures. The idea is that the gesture of one hand controls the drawing actions. The motion and gesture of the other hand control the drawing positions. There are three major steps. First, our system adopts a vision-based bare-hand detection method which computes the hand position and recognizes the hand gestures. Second, the drawing positions and the drawing actions are sent to a sand drawing subsystem. Finally, the subsystem performs the sand drawing actions. Experimental results show that our system enables users to draw a rich variety of sand pictures.

Full textAbstract:
A simplified bubble model and its solver optimization method are proposed to solve the problem of poor realistic simulation and complex solutions for bubble-motion behavior in water. Firstly, the internal velocity of the bubble was avoided, and the bubble model was established by only considering the net flux of the inlet and outlet bubbles, which reduced the computational complexity. The bubble constraint was then introduced into the motion equation of water, and the mixed Euler–Lagrangian method was used to solve it. FLIP particles tracked the bubble position, velocity, and deformation, and the mesh updated the vector field. At the same time, the viscosity term was simplified. Finally, it was combined with implicit incompressible SPH particles to achieve the purpose of volume correction. The experimental results show that the method in this paper can present a simulation effect of bubbles in water with rich detail and a realistic sense, whether compared with actual pictures or with existing methods.

The paper presents an ultra-high-speed image sensor for motion pictures of reproducible events emitting very weak light. The sensor is backside-illuminated. Each pixel is equipped with the multiple collection gates (MCG) at the center of the front side. Each collection gate is connected to an in-pixel large memory unit, which can accumulate image signals captured by repetitive imaging. The combination of the backside illumination, image signal accumulation, and slow readout from the in-pixel signal storage after an image capturing operation offers a very high sensitivity. Pipeline signal transfer from the MCG to the in-pixel memory units enables the sensor to achieve a large frame count and a very high frame rate at the same time. A test sensor was fabricated with a pixel count of 32 × 32 pixels. Each pixel is equipped with four collection gates, each connected to a memory unit with 305 elements; thus, with a total frame count of 1220 (305 × 4) frames. The test camera achieved 25 Mfps, while the sensor was designed to operate at 50 Mfps.

Contemporary display systems are notorious for their lack of flow across display pages. The capabilities to dynamically change the makeup and layout of a display that are resident in windowing and sensor fusion systems are beginning to present the display system designer with even more complex display transition problems. The motion picture industry, on the other hand, has for years successfully presented a series of dynamic visual displays, where changes from one scene (or display) to the next has been accomplished with no notice, or where the change has actually enhanced the information flow to the viewer. This paper discusses how some of the techniques and principles used in making editing decisions might be applied to the design of display systems.

Purpose: A documentary film or documentary is a non-fictional motion picture intended to reflect reality, typically for the goals of instruction, preservation of history, or training. Documentary filming heroines must always be noble, alluring, and seductive, regardless of the type of roles they perform.
Method: The same method of objectification is employed in Michael Bay's “Transformers” film, on the other hand, are what ultimately influence both male and female filmmakers as well as audiences to make sense of the narratives, reasoning, and symbolisms that the media industry, particularly cinema, uses to construct its framework and establish its method of operation.
Result: As a result, it serves as an essential medium for female creative expression and a source of knowledge for women. The mild paradox that results from this is that women are not hired for jobs where past employment is required to prove one's value.
Conclusion: The fallouts of the review provide a more thorough picture of female representation in documentary filming and how viewers have evolved to perceive it through time. Unfortunately, women face a variety of problems in addition to media underrepresentation.

<p><span style="font-size: medium;"><em>9 Summers 10 Autumns</em> (2011) is an inspirational autobiographical novel about a young man from a small city of Batu who later succeeded in pursuing his dream by working in the United States. The novel was written according to Iwan Setyawan’s life story and it has been made into a movie by the same name in 2013. Two years later, the movie was adapted into an augmented motion picture hinted illustrative book which is said to be the first kind to appear in Indonesia that combines novel, comic, app and film together. Somehow this phenomenon has also contributed to the rising trend of films adapted into books in Indonesia, such as <em>Assalamualaikum Beijing</em> (2015), <em>What’s Up with Love?</em> (2016), and others. This study caters for Iwan Setyawan’s strategy in achieving legitimacy in the arena of Indonesian Literature and his American Dream Ideals that are depicted within the book. The discussion is carried out within the perspectives of Pierre Bourdieu’s field of cultural production theory as well as sociology of literature approach in highlighting the phenomenon of transformation from novel into film and eventually into augmented motion picture hinted illustrative book. Later, the study discovers that it has changed the image of Indonesian art and literary world in which such prestigious legitimacy can now be achieved through commercial strategies, making it seem dynamic but at the same time questionable in its most authentic sense. </span></p>

Among many sports, badminton is one of the most popular events and it is deeply loved by people. However, there is relatively little research on pose recognition and prediction of badminton, so this paper uses video image analysis to perform badminton action recognition prediction and action classification. In order to better realize the lower limb movement pattern recognition and motion posture prediction of badminton players, this paper chooses BP neural network algorithm to establish a badminton motion posture recognition and prediction model based on video image analysis. The simulation results of the models are compared, and it is found that the recognition of the motion pose and the prediction model established by the neural network are accurate, and they almost coincide with the actual motion trend. In this paper, a face detection and recognition framework is established. The algorithm is used to filter the pictures of the input recognition network. Through calculation, the average accuracy rate of the face detection algorithm realized in this paper can reach 92.6%. This shows that the face detection algorithm implemented in this paper basically meets the standards. In this paper, a single inertial sensor is used to classify and recognize badminton movements using sensors located on the right wrist, left wrist, waist, and right ankle. This shows that the right wrist is the best position and achieves different strokes.

Recently, with rising public security awareness, the demand for an efficient surveillance system has become highly significant. But, several monitoring systems developed have certain drawbacks limiting their applications. Therefore, a refined surveillance system has been proposed which could be utilized in many fields, especially in border areas for intrusion detection, to reduce the crime rates and to serve tremendous purposes. The project focuses on building a spying robot for maneuvering and monitoring in perilous environments. The module includes Raspberry Pi interfaced with DC motors, GPS, Pi camera, Temperature sensor, Fire sensor and ultrasonic. Meanwhile, the motion of the robot could be controlled by a web application through Wi-Fi connectivity. This robot is programmed to stream the live data over a virtual network and update the captured images along with the time stamp and location at certain instances to the cloud. Hence, it can transmit real-time videos and pictures with temperature measured.

One of the challenges that teachers face when they teach data analysis to their students is getting them to see the “big picture.” Using multiple representations is one way to help students make sense out of a large amount of data. For example, the data can be recorded in a table, graphed in a rectangular-coordinate system, and analyzed for an equation of best fit. These techniques are standard practice in data analysis. However, furnishing an interesting context for teaching these methods is sometimes difficult. One way to motivate students to see the big picture of data analysis is to explore an example from the motion-picture business. Since the release of James Cameron's movie Titanic in December 1997, the film has become a part of the popular culture. It earned more than $1 billion worldwide at the box office, which makes it the highest-grossing film of all time. Inevitable articles and programs documented and commented on the success of this epic film. One article, in particular, in Newsweek was titled “Our Titanic Love Affair” (Ansen 1998). A simple statement of earnings trends appeared in a caption next to a graph showing the longevity of the weekend revenues generated by the movie. It read as follows: “Most hit movies enjoy big opening weekend sales, then revenues decline quickly.” Both the graph and the caption raise two interesting questions: What do the graphs and trends of “most hit movies” look like? And how are the weekend earnings of Titanic different?

In this study, an optical method of real-time displacement measurement of such bridges was carried out by means of digital image processing techniques. A commercially available digital video camera combined with a telescopic device takes a motion picture of the target panel with known geometry, which is installed on the measurement location of a bridge. The displacement of the target is calculated based on the captured images in real-time manner using image processing techniques, which require a texture recognition algorithm, projection of the captured image, and calculation of the actual displacement using target geometry and number of pixels moved. For the purpose of verification of the presented method, a laboratory test was made using shaking table test and the measured displacement by image processing techniques was compared with the data from a contact-type sensor, a linear variable differential transformer (LVDT). The proposed method gave close results to a conventional sensor. Field tests were carried out on a bridge with steel plate girders and a bridge with steel box girders. The test results gave sufficient dynamic resolution in frequency as well as the amplitude.

Lois Weber gave many speeches during her career as a film writer-director, but until now our knowledge of them has been limited to journalistic summaries and brief quoted excerpts. The current article advances our understanding of this dimension of Weber's career (and helps restore her “voice,” in a sense) by providing the text of an entire speech, reconstructed from five primary sources. Weber discussed a wide range of film topics in this public talk, which she delivered to the Los Angeles Woman's Club in July 1913. They included censorship issues, film's educational possibilities, her interest in greater authenticity in films, and her desire to uplift films and to correct the misinformation surrounding what she called “the glamour and danger of motion picture work.” It typifies the many speeches she gave to audiences made up of women who shared her interest in raising the standards of Hollywood and its products.

Conventional home security systems often lack the ability to monitor and respond in real-time, which makes them vulnerable to security breaches and delayed interventions. This research is an Internet of Things (IoT) based home security system that uses hard programming methods. This system consists of hardware that uses Arduino Uno, ESP32CAM and PIR sensor modules to detect movement, an ESP32CAM camera that takes pictures, and an Arduino Uno board that processes and transmits data. ESP32CAM takes images from the PIR sensor and sends them to the cloud server when it detects motion. The smartphone application then allows users to find out about potential disruptions in real-time through photo notifications. The system's ability to provide immediate visual evidence of suspicious activity, allowing for a rapid and informed response, determines the system's effectiveness. This system is also cheap and easy to use, so a wide range of users can use it. The use of easily accessible components and open-source software reduces costs and simplifies setup, enabling widespread adoption of this updated security product

Full textAbstract:
We report three experiments using a new form of direct subjective presence evaluation that was developed from the method of continuous assessment used to assess television picture quality. Observers were required to provide a continuous rating of their sense of presence using a handheld slider. The first experiment investigated the effects of manipulating stereoscopic and motion parallax cues within video sequences presented on a 20 in. stereoscopic CRT display. The results showed that the presentation of both stereoscopic and motion parallax cues was associated with higher presence ratings. One possible interpretation of Experiment 1 is that CRT displays that contain the spatial cues of stereoscopic disparity and motion parallax are more interesting or engaging. To test this, observers in Experiment 2 rated the same stimuli first for interest and then for presence. The results showed that variations in interest did not predict the presence ratings obtained in Experiment 1. However, the subsequent ratings of presence differed significantly from those obtained in Experiment 1, suggesting that prior experience with interest ratings affected subsequent judgments of presence. To test this, Experiment 3 investigated the effects of prior experience on presence ratings. Three groups of observers rated a training sequence for interest, presence, and 3-Dness before rating the same stimuli as used for Experiments 1 and 2 for presence. The results demonstrated that prior ratings sensitize observers to different features of a display resulting in different presence ratings. The implications of these results for presence evaluation are discussed, and a combination of more-refined subjective measures and a battery of objective measures is recommended.

Full textAbstract:
Arnold Genthe's 1915 photograph of Anna Pavlova, taken as she leaps into the air, is perhaps the earliest photograph of free movement in dance (Fig. 1). Unlike many other early images, with long exposure times necessitating static poses or wires to hold up the dancers, this photograph depicts actual movement. This claim to authenticity and actuality is a powerful part of its appeal; looking at the image, viewers are sure that they are witnesses to a faithful reproduction of Pavlova dancing, that they are seeing the dance of the past. Considered in this manner, the photograph is an example of the revelatory power of the camera to show us what has been.However, Genthe's photograph is not a powerful image simply because it is, authentically, of a dancer in motion. It might have mechanically frozen its subject in time, but the photograph communicates movement beyond the moment it depicts—beyond, in a sense, what it reveals photographically to what it evokes in the mind of the viewer. Viewers are able to see movement in details indicative of motion: the flowing fabric of the costume, Pavlova's bodily posture with raised and powerfully muscled thigh, the elevated arm gestures, and the sharply bent and thrusting toes. Additionally, the degree of blur in the photograph provides an indistinctness that is suggestive of something in motion; oddly, the partial obscurity of the picture prompts viewers to imagine more than they can see. All of these elements are evocative indications of movement; they are neither documentary nor part of what can be called photographic revelation, but are instead representational.

The article summarizes and systematizes modern high-tech digital tools that allow modeling the behavior of a modern consumer and ensuring the efficiency of the functioning of trade enterprises by increasing sales. It has been established that merchandising has an impressive arsenal of high-tech tools, which include: projection showcase, interactive showcase, virtual shelf, 3D showcase, Aislelabs and Prism Skylabs devices, mobile applications, Fetch Robotics and Lowe's robots, ERP system, Amazon Prime Air system, etc. A projection showcase is a showcase glass (screen) covered with a special film (opaque, translucent or completely transparent) of rear projection. A projector is installed behind the screen, which transmits an image to the screen, which is clearly visible from the outside. An interactive showcase (interactive wall, touch showcase) is a video screen that interacts with a person; most often, they use multitouch technology (touch showcases) and contactless sensor technology (Kinect showcases). A virtual shelf is an LCD panel or video wall, with a Kinect system attached to the back, which “reads” human movements and allows you to control the system from a distance. The 3D showcase is an electronic counter with technology that allows 3D images to be literally projected in the air, combined with motion sensors. The motion sensor allows the showcase to react to the trajectory of passers-by, that is, the showcase is static as long as no one walks past it, and as soon as the sensors detect the movement of a person in the reach, the showcase comes to life, the colors, lighting, picture change. Digital technologies in retail are a new interactive advertising tool for attracting and retaining customer attention. Due to the effect of surprise inherent in all interactive solutions in advertising, virtual showcases (interactive walls) attract attention, keep the visitor for a long time, stimulate to make a purchase or receive information.

Background: A breast-specific photoacoustic imaging (PAI) system prototype equipped with a hemispherical detector array (HDA) has been reported as a promising system configuration for providing high morphological reproducibility for vascular structures in living bodies. Methods: To image the vasculature of human limbs, a newly designed PAI system prototype (PAI-05) with an HDA with a higher density sensor arrangement was developed. The basic device configuration mimicked that of a previously reported breast-specific PAI system. A new imaging table and a holding tray for imaging a subject's limb were adopted. Results: The device’s performance was verified using a phantom. Contrast of 8.5 was obtained at a depth of 2 cm, and the viewing angle reached up to 70 degrees, showing sufficient performance for limb imaging. An arbitrary wavelength was set, and a reasonable PA signal intensity dependent on the wavelength was obtained. To prove the concept of imaging human limbs, various parts of the subject were scanned. High-quality still images of a living human with a wider size than that previously reported were obtained by scanning within the horizontal plane and averaging the images. The maximum field of view (FOV) was 270 mm × 180 mm. Even in movie mode, one-shot 3D volumetric data were obtained in an FOV range of 20 mm in diameter, which is larger than values in previous reports. By continuously acquiring these images, we were able to produce motion pictures. Conclusion: We developed a PAI prototype system equipped with an HDA suitable for imaging limbs. As a result, the subject could be scanned over a wide range while in a more comfortable position, and high-quality still images and motion pictures could be obtained.

The article is devoted to the analysis of methods of stabilization of photo-video camera and image, advantages and disadvantages of different methods of camera stabilization in order to improve the quality of photo and video shooting. The optical image stabilization system is an automated control system. In its composition, it must have a motion sensor, such as a gyroscope or accelerometer, analog or digital computing device and an actuator for motion compensation (motor). The purpose of such a control system is to maintain a fixed position relative to the inertial coordinate system, line of sight or light beam that passes through the camera lens and falls on the light-sensitive matrix. It is possible to realize it by means of the electric motor on the basis of the information from sensors. The electric motor rotates a certain stabilized optical unit, which in turn refracts the light beam. This unit is made with the possibility of rotation around the vertical and horizontal axes or the axes of the course and pitch. The optical unit rotates so that the projection of the image on the film or light-sensitive matrix fully compensates for camera shake during exposure. As a result, the projection always remains stationary with respect to the light-sensitive matrix for small oscillations of the camera. This provides the necessary image clarity. The steadic camera stabilization device provides smooth camera movement in different planes. Steadicams are used in film and video shooting, as it is the easiest way to get a quality picture in motion without shaking with minimal cost. To ensure high accuracy of image stabilization, it is proposed to use an optical stabilization system based on image stabilization. It can be used for photo and video equipment and even in systems such as binoculars and sights.

Abstract The surveillance system has been utilized over the years on public property in order to provide security and prevent unauthorized entrance. Lately, more private homeowners are choosing to implement security systems. There are many problems with the video surveillance system. These disadvantages are the indistinctiveness of the pictures/video and the need for a lot of storage space to save surveillance information. This paper describes the design and implementation of a low-cost Web Monitoring System based on Raspberry Pi. Also, a web application is designed for the purposes of controlling the camera and for live streaming. The live stream from a web camera can be viewed from any web browser, even mobile, in real-time. Controlling the camera is possible with the web application using four commands (up/down, left/right). Also, the camera moves depending on the detection of an object located in the visible area of the PIR Motion sensor, thereby issuing a warning message about object detection.

Since early 2007, many ambitious DSC manufactures in Japan have paid special attention for built in digital effects, in order to create better quality of picture, such as: Face Detection, Smile Shutter Mode, Full frame CCD, Anti Shake system, Live View, CMOS sensor..., which were highly appreciated by many photo fans around the world, and created hot-selling record on favorite model. In fact, these fancy “Digital Technologies” could be standardized in selected new cameras right now. In late 2009, new artificial intelligence image chips such as: back-illuminated CMOS image sensor, 30x Optical Zoom (or more), Full HD Video, Sweep Panorama, Interchangeable Unit Camera System,Super High Speed ISO, Super Steady, Motion Remover.., have been promoted in new generation of camera. It could change not only the performance of new camera (DSC/DC) but to challenge the current DV market seriously, and may inspire new record-high selling again. In our experiment, we collect more than 300 cases from the telephone survey during Sep, 2010 and Dec, 2010. Total of 220 cases comply with the conditions. To probe mainly into the relationship between new generation DC Confidence level and 3 potential customers: Amateur Photographer (AP), Senior Photographer (SP), and college student (CS). That is the reason what we are probe into this highly competitively market with brilliant creative design, and hope to offer an objective suggestion for both industry and education administers.

This article is the result of a book review of a work by Stefano Gattei. The starting point of Popper's view is that "almost every phase of our scientific development is under metaphysical rule, that is, ideas that are tested, ideas which determine not only what problems we need to explain, but also what kinds of answers we will consider to be one that is important or satisfactory or accepted, and as a remedy, or guarantee, of a previous answer". Popper's indeterminism is important because Popper's custom begins by considering an intuitive Laplacian view of determinism: "the world is like a motion picture film: or a projected image. Parts of the film have proved to be the past. And unproven people are the past. front". Popper has always been claimed to be a metaphysical realist: to him, to be a realist means to think, in covenant with common sense, that the world of his existence is independent of human beings. It means, "my existence will end without the world coming to an end too". As well as other metaphysical positions, realism is a non-testable conjecture: "realism is neither proven nor disproved".

Farmland security in Nigeria is still a major challenge and existing methods such as building brick fences around the farmland, installing electric fences, setting up deterrent plants with spikey branches or those that have displeasing scents are no longer suitable for farmland security. This paper presents an IoT based farmland intrusion detection model using sensors and computer vision techniques. Passive Infrared (PIR) sensors and camera sensors are mounted in strategic positions on the farm. The PIR sensor senses motion by the radiation of body heat and sends a message to the raspberry pi to trigger the camera to take a picture of the scene. An improved Faster Region Based Convolutional Neural Network is developed and used for object detection and One-shot learning algorithm for face recognition in the case of a person. At the end of the detection and recognition stage, details of intrusion are sent to the farm owner through text message and email notification. The raspberry pi also turns on the wade off system to divert an intruding animal away. The model achieved an improved accuracy of 92.5% compared to previous methods and effectively controlled illegal entry into a farmland.

Abstract The present paper describes the development of a mobile platform as a support of the real estate appraisal procedure. Currently, the estate evaluation is performed by an expert that manually collects data, performs measurements, and grabs pictures of the inspected unit to finally evaluate its commercial value. The READ project aims at automatizing this process by developing a solution based on a mobile unit (drone or tablet) able to navigate the indoor environment and record data, which will be later processed on the cloud. To accomplish all these tasks, the platform is equipped with cameras, a LiDAR sensor, and a data process unit, with the goal of 1) understanding its motion and localization; 2) reconstructing a 3D map of the inspected space; 3) performing image-based analyses applying AI algorithms enabling the identification of the indoor space (e.g. bedroom or kitchen), the counting and the classification of furniture objects, and the detection of building imperfections or frauds. Tests have been performed in different scenarios providing promising results, laying the foundations for bringing these technologies into a real operational context.

Relevance. Neurological disorders are one the most frequent cause for developing of chronic foot inflammation. Analysis of pathological picture of chronic osteomyelitis in patients with neurogenic foot deformities, including cases of spina bifida, is not adequately addressed.Purpose of the study — to examine morpho-functional aspects of chronic osteomyelitis in patients with multicomponent foot deformities and with spina bifida.Materials and Methods. The present paper is based on the study of 30 patients with multicomponent neurological foot deformities complicated by chronic osteomyelitis who had medical history of spina bifida (myelomeningocele type). Histology was used to examine resected fragments of affected bone tissue, bone sequestration and skin adjacent to osteomyelitis area. Laser doppler flowmetry was used to study capillary cutaneous blood flow on plantar foot surface. Thermal and pain sensitivity was assessed by electric sensimeter in L4, L5, S1 dermatomas on the right and on the left sides.Results. Biopsy skin specimens harvested at osteomyelitis area demonstrated signs of parakeratosis, absence of stratum lucidum, epidermis acanthosis with 25% thickness increase (р = 0,04), 2,2 times increase of density for microvessels of the dermis (р = 0,73Е-4) and increased rate of capillary blood flow at 81,6±14,2% (р = 0,0004), fibrosis and dermis thinning at 19,1% (р = 0,03), 1,37 times increase in bulk density of perspiratory glands (р= 0,04), loss of adipose tissue and degeneration of nerve fibers in the majority of nerve stems of the dermis. Above factors were accompanied by disorders in thermal and pain sensitivity in 100% of cases and in 29% of those sensitivity was missing. Morphological picture of bone tissue in osteomyelitic area was manifested by multiple destruction cavities with pyogenic membrane, granular tissue of varying maturity, combined chronic and acute stages of the process, and by poor restorative bone formation.Conclusion. Disorders or lack of thermal and pain sensitivity in dermatomas L4, L5, S1, of safety sense and motion control, resulting chronic load on atypical foot segments, as well as patho-histological skin alterations contribute to ulcer formation and osteomyelitis in patients with spina bifida and multicomponent foot deformities. Morphological picture of foot bony tissue at osteomyelitic site indicates typical patho-morphological signs of chronic inflammation with poor restorative bone formation.
