Abstract:

Despite mixed results, state government use of targeted economic development programs has escalated. This study evaluates the impact of motion picture incentive programs, an array of tax incentives employed by over 40 states to entice film and television productions out of California and New York, on labor and economic conditions from 1998 through 2013. Results suggest that sales and lodging tax waivers had no effect on any of four different economic indicators. Transferable tax credits had a small, sustained effect on motion picture employment levels but no effect on wages. Refundable tax credits had no employment effect and only a temporary wage effect. Neither credit affected gross state product or motion picture industry concentration. Incentive spending also had no influence. These findings demonstrate the heterogeneous impacts of different incentives offered under a single program and should inform future economic development policy design.

Abstract:

Two different kinds of metallic plates on a rotating disk target were irradiated with a MeV proton beam, and quasi-monochromatic pulsed X-rays with different energies around the absorption edge of the contrast medium were alternately produced. By using these dual-energy X-rays and a high-sensitivity X-ray movie camera, we took a motion picture of the transmission image of a periodically moving phantom, which simulated a rat heart as a test animal. We found that the enhanced movie imaging of the contrast agent is available by subtraction between adjacent picture frames.

Full text

Abstract:

This article examines the role of animation in early instructional medical films through close analysis of the films produced by the collaboration between the American College of Surgeons (ACS) and Eastman Kodak in the late 1920s. The ACS placed medical motion pictures at the center of surgical training and thus established moving images as fundamental to the practice of medicine. These films made extensive use of animation to present surgical sequences that were otherwise impossible to capture on film. By adopting the motion picture as an educational tool, the physician–filmmakers actively constructed medical reality through representations that depended on artifice to convey objective scientific truths. ‘Actual photography’ and animation were blended to visualize the invisible and simplify explanations by reducing the information contained in the visual image. The films simultaneously demonstrate how the motion picture camera served as a tool for medical documentation, training both their objects (the patients) and their subjects (the doctors) in the process.

Abstract:

This paper describes the way to obtained the transverse motion trajectories of aeolian saltation sand by high-speed digital camera. With the assumption that the background images of the static bed surface on two consecutive pictures were uniform, the saltation sand images on each picture were distinguished from the background image of the bed surface by means of a series of image operation processing used on three sequential pictures. Then the transverse motion trajectories of saltation sand were obtained using the superimpose algorithm and the labeling algorithm. The results show that the transverse motion should be taken into consideration when modeling saltation in air.

Abstract:

In the early 1940s Japan, cinematographers and critics feverishly discussed the notions of immediacy and authorship in relation to documentary practices. The status of cinematographers as the authors of the images that they shot was particularly questioned in those conversations due to the mechanical nature of the motion picture camera. This article mainly focuses on the discussions in the journal Eiga Gijutsu (Film Technology) in 1941–1942 over the notion of culture, and examines how cinematographers imagined their new roles in documentary practices in the cinema.

Abstract:

Purpose. We evaluated the potential utility of a cost-effective 4K consumer video system for surgical education in ophthalmology. Setting. Tokai University Hachioji Hospital, Tokyo, Japan. Design. Experimental study. Methods. The eyes that underwent cataract surgery, glaucoma surgery, vitreoretinal surgery, or oculoplastic surgery between February 2016 and April 2016 were recorded with 17.2 million pixels using a high-definition digital video camera (LUMIX DMC-GH4, Panasonic, Japan) and with 0.41 million pixels using a conventional analog video camera (MKC-501, Ikegami, Japan). Motion pictures of two cases for each surgery type were evaluated and classified as having poor, normal, or excellent visibility. Results. The 4K video system was easily installed by reading the instructions without technical expertise. The details of the surgical picture in the 4K system were highly improved over those of the conventional pictures, and the visual effects for surgical education were significantly improved. Motion pictures were stored for approximately 11 h with 512 GB SD memory. The total price of this system was USD 8000, which is a very low price compared with a commercial system. Conclusion. This 4K consumer camera was able to record and play back with high-definition surgical field visibility on the 4K monitor and is a low-cost, high-performing alternative for surgical facilities.

Abstract:

Most anti-shake technologies can compensate the hand shake when taking a static picture. When people use the camera in the dim environment, the shutter opening time will be extended to increase exposure. However, the hand shake will cause the photos blurry if the shutter opening time was too long. The hand shake problem is even more serious when people doing the dynamic image recording. In the past years, the mobile phones with the digital camera and portable video camera were developed vigorously. Taking pictures and recording dynamic image have become the basic functions of mobile phones since the development of the 3G mobile phone. While the specifications of cameras become high resolution and high magnification optical zoom, the traditional electronic anti-shake technology will not be applied in the digital camera because of the large amount of computing power. It is also difficult to apply the optical anti-shake technology in thin 3C products because the volume of optical anti-shake module is too large. Thus, developing a new anti-shake technology which can be applied in the thin 3C products to enhance the photo and video quality is very important. In this paper, the image processing technologies will be applied to calculate the motion signal. Then, the voluntary and involuntary motion signals will be separated by the signal separation algorithm, and finally the dynamic image will be reconstruction by compensating the involuntary shake of each frame to enhance the quality of the dynamic image.

Full text

Abstract:

This article proposes a reconceptualization of the term “actor” within motion pictures and presents the argument that “acting” is a matter of distributed agency performed by heterogeneous assemblages. What constitutes an actor is what I will label as a “cinematic actor assemblage,” a term that comprises what is commonly known as human actors as well as material entities that play an active part in motion picture images. The use of intra-diegetic cameras in contemporary found footage horror films constitutes a particular case of such cinematic actor assemblages. Through a dynamic relational performance, cameras here take on roles as active agents with the potential to affect other elements within the images as well as the films’ audiences. In found footage horror the assemblage mode of operation creates suspense, since the vulnerability of the camera threatens the viewer's access to the depicted events. While human characters and individual entities making up the camera assemblage are disposable, the recording is not. Found footage horror crucially hinges upon the survival of the footage. I will further suggest that these films allow filmmakers to experiment with the acting capabilities of intra-diegetic cameras.

Abstract:

Discourse encompasses not only written and spoken language but visual images as well. If discourse combines visuals and images, it is important that analysis of such texts account for the special characteristics of visual semiotics; the relationship between language and images. Using Critical Discourse Analysis (CDA), this paper, unravels power relations in the electronic advertising texts such as those aired on television. The targeted television advertising discourse is characterised by sound, colour, picture, camera angle and other motion picture attributes. The paper argues that texts in general and texts as adverts are hegemonic in nature. The reproduction of a popular culture perpetuated by adverts has been noted to support the perspective that advertising drives the global media and has profound influence on the content of the media messages received and subsequently on the cultures of the recipients. The paper makes use of the McDonalds TV Seat Advert shown on SABC1.

Abstract:

ArgumentFrom 1924 to 1948, developmental psychologist Arnold Gesell regularly used photographic and motion picture technologies to collect data on infant behavior. The film camera, he said, records behavior “in such coherent, authentic and measurable detail that . . . the reaction patterns of infant and child become almost as tangible as tissue.” This essay places his faith in the fidelity and tangibility of film, as well as his use of film as evidence, in the context of developmental psychology's professed need for legitimately scientific observational techniques. It also examines his use of these same films as educational material to promote his brand of scientific child rearing. But his analytic techniques – his methods of extracting data from the film frames – are the key to understanding the complex relationship between his theories of development and his chosen research technology.

Abstract:

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.

Full text

Abstract:

The foil bearing consists of parts made of very thin, properly shaped foils. Usually, it is very difficult or even impossible to measure the vibrations of these elements during the bearing operation using traditional sensors. Therefore, the authors of this article have proposed an entirely new approach to this issue. This article discusses the analysis of vibrations of the structural supporting layer of a gas foil bearing at high rotational speeds. Instead of using a traditional method to measure the bearing journal movement, the measurement was performed using an ultra-high-speed digital camera. This type of measurement was used for the first time to analyse foil bearing displacement. It turned out that doing so can give a far more vibrant picture of what is happening in gas foil bearings during their operation. The article includes an analysis of foil vibrations. This phenomenon has already been analysed numerically, and this is the first time it has been analysed experimentally. The registered motion of the foils can be compared with the results obtained from numerical models, thus allowing their further development. One such comparison is shown in this article.

Abstract:

The purposes of this study were (a) to describe the techniques used by elite female athletes during the transition from approach to takeoff in the long jump and (b) to determine which characteristics were significantly related to the officially recorded distance of the jump. The subjects were the 12 finalists in the Women's Long Jump at the 1984 Olympic Games. A motion-picture camera placed with its optical axis at right angles to the runway was used to record the performances of the subjects. Means and standard deviations of the variables identified in a theoretical model and correlations between these variables and the distance of the jump were computed. Significant correlations revealed that the less the downward velocity at touchdown at the end of the third-last stride, and the less this velocity is changed by the vertical forces transmitted via the supporting foot, and the shorter the duration of the next flight phase, the greater the distance of the jump.

Abstract:

Artificial blood pump assistance of the failing human heart can allow it to recover. Analysis of blood pump fluid flow is a useful tool for design development and thrombosis minimization. The aim of this study was to investigate fluid flow, particularly ventricular clearance rate and stagnation areas, in four different blood pump geometries and to determine the best design. The blood pumps consisted of a polyurethane ventricle, and combinations of inlet/outlet pipe angles and compression plate shapes. A video camera recorded the motion of fluid labelled with an optical tracer (Methyl Blue histological dye). A novel processing method was developed to produce colour maps of tracer concentration, experimentally calibrated. An overall picture of fluid flow in each pump geometry was generated by considering clearance curves, tracer concentration maps and inflow jet animations. Overall and local mixing coefficients are calculated for each pump. The best geometry featured straight inlet/outlet pipes and a domed compression plate. This optical tracer technique has proven convenient, economical, sensitive to low concentrations of tracer and provides instantaneous pictures of tracer distribution in a ventricle.

Abstract:

An inverse analysis of the pole vault was completed using a nine-segment rigid-body model of the vaulter in two dimensions. Competitive vaults by five elite vaulters were recorded on film using a high-speed 16-mm motion picture camera. The films were digitized and the digitized data were smoothed. The resultant joint moment histories at the shoulder, left hip, left knee, right hip, and right knee were computed for each vaulter. The moments produced about the top hand by the lower hand on the pole were also computed. The resultant joint moments at each joint were compared between vaulters and related to observed vault techniques. The moment produced by the lower hand on the pole and the resultant shoulder moment showed the most variance between vaulters. The pole moment indicated that the lower arm pulled on the pole throughout much of the vault. The resultant shoulder joint moment indicated the need for strength in the shoulder joint extensor muscles. Variations in the resultant moments at the lower extremity joints were small despite large apparent differences in the observed kinematics between vaulters.

Abstract:

The purpose of this study was to determine the mechanical factors that govern success in the performance of the handspring and salto forward tucked vault. The subjects were the 41 all-around gymnasts participating in the 1986 USA Gymnastics Championships. A motion-picture camera placed with its optical axis at right angles to the runway was used to record the performances of the subjects. Significant correlations indicated that the horizontal velocity at takeoff from the board was an important determinant for successful results, and also that the more the gymnast’s focus was on horse contact or blocking and the more vertical the direction of his effort at takeoff into the postflight, the better the final result. Quite unexpectedly, significant correlations revealed that the greater the relative height of takeoff from the horse and the less the height of CG at landing on the mat, the greater the points awarded by the judges. These relationships were almost entirely a consequence of the landing angle. Rationale for these findings were based on close observations of the filmed performances and the correlational analyses.

Abstract:

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.

Abstract:

Computer three-dimensional animation is a new type of animation with the development of computer software and hardware technology in recent years. Three-dimensional animation should apply the software of three-dimensional animation technology to establish a virtual world in the computer. In this virtual three-dimensional world, designers build animated character models and scene models according to the shape and scale of the objects to be represented. Then set the motion trajectory of the character model, the motion of the virtual camera and other animation parameters according to the requirements, and then assign specific materials to the model and add lights to the model. Then the computer can automatically calculate and generate the final continuous picture. Under this background, the research on 3D animation character shaping in this paper is to analyze and study the market situation from the standpoint of small-scale 3D animation companies (teams) with relatively weak technology, and through the author's own creative practice, this paper summarizes some principles for the design and production of 3D animation characters, and tries to improve the education system of 3D animation character design. It promotes the production and dissemination of 3D animation and distinct 3D animation characters. Starting with the comparative research method, this paper summarizes the differences of 3D animation character shaping from the comparison of the characteristics of 3D animation and traditional animation, and then summarizes the efficient ways and methods of how to shape 3D animation characters by combining practice with theory.

Abstract:

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.

Full text

Abstract:

AbstractIn the late 1920s, the American obstetrician Joseph DeLee brought the motion-picture camera into the birth room. Following that era's trend of adapting industrial efficiency practices for medical environments, DeLee's films give spectacular and unexpected expression to the engineering concept of ‘streamlining’. Accomplishing what more tangible obstetric streamlining practices had failed to, DeLee's cameras, and his post-production manipulation, shifted birth from messy and dangerous to rationalized, efficient, death-defying. This was film as an active and effective medical tool. Years later, the documentarian Pare Lorentz produced and wrote his own birth film, The Fight for Life (1940). The documentary subject of the film was DeLee himself, and the film was set in his hospitals, on the same maternity ‘sets’ that had once showcased film's remarkable streamlining capacity to give and keep life. Yet relatively little of DeLee was retained in the film's content, resulting in a showdown that, by way of contrast, further articulated DeLee's understanding of film's medical powers and, in so doing, hinted at a more dynamic moment in the history of medicine while speaking also to the process by which that understanding ceased to be historically legible.

Abstract:

The purpose of this study was to determine mechanical factors, through development of the deterministic model, that govern successful performance of the handspring vault. The subjects were 40 elite male gymnasts participating in the 1987 Pan American Games. A motion-picture camera placed with its optical axis at right angles to the runway was used to record the subjects’ performances. Significant correlations indicated that the following were important determinants for success: (a) large horizontal velocity and angular momentum at takeoff from board, (b) shorter time of preflight and smaller relative height of takeoff in preflight, (c) large horizontal breaking force and large vertical force exerted as well as a large loss of angular momentum during horse contact, and (d) large vertical velocity of takeoff from horse. Significant correlation of “on-horse” factors with the judges’ scores indicated that the more the gymnast focused on horse contact and the more vertical the direction of his effort at takeoff, the better the final result. A significant negative correlation revealed that the less the height of CG at touchdown on mat, the more points awarded by judges. This relationship was almost entirely a consequence of the landing angle.

Abstract:

The 25 highest scored Hecht vaults (G!) performed during the 1995 World Championships were compared with those receiving the 25 lowest scores (G2). Hypotheses were: GI would achieve (a) larger kinetic energy at takeoff from the board and the horse, (b) greater displacements of CM and greater forward body rotation in prellight. (c) greater changes in velocities and angular momentum on horse, (d) more rapid, forceful blocking/pushing off the horse, and (e) greater “amplitude” and better “form” during the post-flight than G2. A 16-mm motion picture camera, operating at 100 Hz. recorded the vaults during the compulsory competition. The results of t tests (p < .005) indicated Gl had (a) larger kinetic energy at takeoff from the board and the horse, (b) greater displacements of CM and greater forward body rotation in pre-flight. (c) greater changes in vertical velocity and angular momentum on the horse. greater vertical impulse of high force and short duration exerted on the horse, and greater “amplitude,” greater backward body rotation, and greater body extension in post-flight than G2. In conclusion, successful performance of the Hecht vault is likely when focus is on sprinting the approach, blocking and pushing off the horse rapidly and vigorously downward, and maintaining the fully extended body position throughout the post-night to display “form” or fish-like body position for a virtuosity bonus point and simultaneously to prepare for a controlled landing on the mat.

Abstract:

To design effective and efficient fish passage facilities at hydropower plants, the knowledge of swim behaviour of fish is essential. Therefore, living wild fish were investigated at different fish guidance structures in an experimental flume in a test section of 11 m length and 2.5 m width at water depths of about 0.6 m. Besides analysis of time data and manual recordings of the fish behaviour, video recordings of the fish movements can allow more detailed analysis of fish behaviour in different hydraulic situations. Thus, a videometry system was installed consisting of eleven synchronous cameras with overlapping views lined-up under dry conditions outside the flume. A 3D tracking algorithm was developed and implemented to analyse the video data. Core of the code is a motion-based multiple object tracking method, in which several objects can be tracked in 2D pixel-frame coordinates at the same time. After undistorting and stereo-calibrating the cameras, the 2D tracks are transferred to a 3D metric-space according to their epipolar geometry. Within this paper video data from a single experimental run of 15 min with three fishes with lengths of 100–150 mm are analysed exemplarily. The path-time diagram gives a distinct ‘big picture’ of the fish movement, which helps to identify preferred and disliked regions. However, due to imperfect actual camera setup, a 3D view in the near field of the cameras and an automated separation of individual tracks in a group of fish remains challenging.

Abstract:

Our recent studies show that intravenous administration of capsaicin induces enhancement of the intralaryngeal thyroarytenoid (TA) branch but a reduction of the intralaryngeal abducent branch, suggesting that the glottis is likely closed by capsaicin. The aim of the present study was to examine whether the glottis is adducted by intravenous administration of capsaicin. Electromyographic (EMG) activity of the TA muscle, subglottal pressure (SGP), and glottal behavior were evaluated before and after intravenous administration of capsaicin in male Wistar rats that were anesthetized and tracheostomized. Catheters were placed in the femoral artery and vein, as well as in the right jugular vein. Low and high doses of capsaicin (0.625 and 1.25 μg/kg) produced apnea and increases in the amplitude of the TA EMG. This enhancement of the TA EMG was observed during apnea as well as during recovery from apnea. Moreover, the onset of the TA EMG was advanced such that it commenced earlier during inspiration. Concomitantly, the SGP substantially increased. Increases in both the TA EMG and SGP were abolished after bilateral sectioning of the recurrent laryngeal nerve. In some animals, movement of the vocal folds was recorded by taking a motion picture with a digital camera under a surgical microscope. With intravenous administration of capsaicin, a tight glottal closure, decreases in blood pressure, and bradycardia were observed. These results strongly suggest that glottal closure is reflexively induced by intravenous administration of capsaicin and that closure of the glottis is beneficial for the defense of the airway and lungs when an animal is exposed to environmental irritants.

Abstract:

Camera captured image is a set of three-dimensional picture frame. This picture frame is a set of different characteristics and parameters. Captured picture suffers from image blurring parameters. These blurring parameters are created by camera misfocus, motion, atmospheric causes, camera sensor noise etc. Thus, captured picture is represents the blurry image format due to lot of interferences occurs in the surrounding background and picture captured device. Hence, some information is corrupted i.e. degradation occurs in the camera captured picture. Therefore, it needs to reconstruct the original picture using image restoration process. Restoration operation includes different image deblurring algorithms such as Non-blind deconvolution and Blind deconvolution algorithms. Non-blind deconvolution algorithms are more effective when blurring parameters of captured picture is known but Blind deconvolution algorithm recover the blurry image without prior knowledge about blurring parameters.

Abstract:

Recently, optical wireless communication (OWC) technologies focused on a camera or an image sensor receiver have drawn specific attention in areas like the internet, indoor localization, motion detection, and intelligent transportation systems. Besides, panorama sensors are the subject of communications from picture sensors as receptors as the high-speed OWC strategy do not need any change to the existing network, so the difficulty and expense of deployment are very limited. So in this paper, a detailed review of the techniques of optical camera communication (OCC)has been presented. In addition to their function of localizing, tracking and recording motion. Through addressing several facets of OCC and their different implementations, this study varies from the latest literature on this topic. The first section of the current article is on standardization, Path classification, modulation, scripting, synchronization, and signal processing methods for OCC networks whereas the second section of the research discusses OCC-based localization, navigation, motion detection, and smart transport systems literature .Finally , OCC's problems and potential work directions have been addressed in the final section of the research.

Abstract:

The objective of this paper is to utilize a webcam to lively track the region of interest (ROI), in particular, the hand locale, in the picture extend and recognize hand motion, we use skin colour discovery and also morphology to delete the unnecessary background information from the picture, and afterward use foundation subtraction to recognize the ROI. Next, to stay away from foundation effects on items or commotion influencing the ROI, we utilize the kernelized connection channels (KCF) calculation to follow the identified ROI. The picture size of the ROI is at that point resized to 28x28 and afterward sent into the profound convolutional neural system (CNN), so as to distinguish various hand signals. Two profound CNN designs are created right now are altered from DenseNet . At that point, the above procedure of following and acknowledgment is rehashed to accomplish a moment impact, and the framework's execution proceeds until the hand is removed from the camera.

Abstract:

Technologies for coding non-camera-captured video contents have received great interests lately due to the rapid growth of application areas such as wireless display and screen sharing, etc. In response to the market demands, the ITU-T Video Coding Expert Group and ISO/IEC Motion Picture Expert Group have jointly launched a new standardization project, i.e. the High-Efficiency Video Coding (HEVC) extensions on screen content coding (HEVC SCC). Several new video coding tools, including intra block copy, palette coding, adaptive color transform, and adaptive motion resolution, have been developed and adopted into HEVC SCC draft standard. This paper reviews the main features and coding technologies in the current HEVC SCC draft standard, with discussions about the performance and complexity aspects compared with prior arts.
