Abstract:

The article is devoted to the problem of providing users with the necessary qualitative indicators of remote video service provision. The imbalance between the reliability of the received video image and time delays in the process of delivering such an image via wireless communication channels is substantiated. For this purpose, the article proposes to use an integrated method of technological solutions, which is connected with the technological processes of reducing the bit intensity of the video stream. It is justified that reducing the intensity of the video stream is achieved by eliminatin

Abstract:

Currently, unmanned aerial vehicles have found wide application in various spheres of the national economy. FPV control refers to a method of controlling unmanned aerial vehicles in which the video stream from the unmanned aircraft is transmitted to the remote pilot station in real time. Due to failures in the communication network, packets with video stream data may be lost or delayed and be delivered late. One of the ways to compensate for the drop in FPS in case of frame loss or delay at the remote pilot station is to predict intermediate frames of the video stream. This paper presents a sc

Abstract:

Everyday tones of video signals are generated, transmitted, and analyzed. The video contents are created for educational purposes, entertainment purposes, surveillance purposes, medical imaging purposes, weather forecasting, satellite imaging, and many other significant places. During the different phases of video content preparation, transmission, and analysis some unwanted signals get interfered with the true contents. Particularly, the medical imaging signals, since they are weak signals, are more prone to unwanted interferences. Such unwanted interference of the noise signals makes it diff

Abstract:

Detecting objects in a video stream is a typical problem in modern computer vision systems that are used in multiple areas. Object detection can be done on both static images and on frames of a video stream. Essentially, object detection means finding color and intensity non-uniformities which can be treated as physical objects. Beside that, the operations of finding coordinates, size and other characteristics of these non-uniformities that can be used to solve other computer vision related problems like object identification can be executed.

Abstract:

Humans show micro-expressions (MEs) under some circumstances. MEs are a display of emotions that a human wants to conceal. The recognition of MEs has been applied in various fields. However, automatic ME recognition remains a challenging problem due to two major obstacles. As MEs are typically of short duration and low intensity, it is hard to extract discriminative features from ME videos. Moreover, it is tedious to collect ME data. Existing ME datasets usually contain insufficient video samples. In this paper, we propose a deep learning model, double-stream 3D convolutional neural network (D

The article proposes a method for selecting blocks for embedding digital watermarks in video files. The video stream is represented as a three-dimensional object. For embedding digital watermarks, the Koch-Zhao method is used, which is generalized to the three-dimensional case. The main goal of the proposed method is to reduce visible distortions from embedding data. For the selection of blocks, their statistical analysis is performed. The variance of the color intensity of individual pixels is chosen as the main parameter. A computer experiment is conducted. To assess the level of visibility,

Millions of videos are uploaded each day to Youtube and similar platforms. One of the many issues that these services face is the extraction of useful metadata. There are a lot of tasks that arise with the processing of videos. For example, putting an ad is better in the middle of a video, and as an advertiser, one would probably prefer to show the ad in between scene cuts, where it would be less intrusive. Another example is when one would like to watch only through the most interesting or important pieces of video recording. In many cases, it is better to have an automatic scene cut detectio

Abstract:

Recently, researchers have turned their focus to predicting the age of people since numerous applications depend on facial recognition approaches. In the medical field, Alzheimer’s disease mainly depends on patients’ ages. Multiple methods have been implemented and developed to predict age. However, these approaches lack accuracy because every image has unique features, such as shape, pose, and scale. In Saudi Arabia, Vision 2030, concerning the quality of life, is one of the twelve initiatives that were launched recently. The health sector has gained increasing attention as the government has

A decisive measure for distinguishing between these explanations is whether or not simultaneously observed up- and down-shifted enhancement occur simultaneously, or if they are the result of temporal and/or spatial averaging. The EISCAT Svalbard Radar has two antennas in the same radar system, which can be used as an interferometer when pointed parallel.

Abstract:

The fluid mechanics and heat transfer characteristics of film cooling are three-dimensional and highly complex. To understand this problem better, an experimental study was conducted in a low-speed wind tunnel on a row of six rectangular jets injected at 90 deg to the crossflow (mainstream flow). The jet-to-crossflow velocity ratios (blowing ratios) examined were 0.5, 1.0, and 1.5, and the jet spacing-to-jet width ratio was 3.0. No significant temperature difference between jet and crossflow air was introduced. Mean velocities and six flow stresses were measured using a three-component laser-D

Abstract:

Introduction. In modern sowing complexes, the process of transporting and distributing seeds and fertilizers is carried out using an air stream. When simulating the technological processes of these pneumatic systems using computational fluid dynamics and discrete elements, an important step is determining the parameters of the interphase interaction of two-phase air – seed and air – fertilizer flows. Both the possibility of implementing models with computational methods and the complexity of the models used depend on the intensity of interphase interaction.Aim of the Study. The aim is to estim

We propose an algorithm to handle the problem of detecting abnormal events, which is a challenging but important subject in video surveillance. The algorithm consists of an image descriptor and online nonlinear classification method. We introduce the covariance matrix of the optical flow and image intensity as a descriptor encoding moving information. The nonlinear online support vector machine (SVM) firstly learns a limited set of the training frames to provide a basic reference model then updates the model and detects abnormal events in the current frame. We finally apply the method to detec

During the rainy season, many public outdoor crimes have been caught through video surveillance, and they do not have complete feature information to identify the image features. Rain streak removal techniques are ideal for indexing and obtaining additional information from such images. Furthermore, the rain substantially changes the intensity of images and videos, lowering the overall image quality of vision systems in outdoor recording situations. To be successful, the elimination of rain streaks in the film will require an advanced trial and error method. Different methods have been utilize

Introduction. Fire detection systems plays an important role in protecting objects from fires and saving lives. In traditional fire detection systems, fire detectors detect fires by combustion of by-products, such as smoke, temperature, flame radiation. This principle is effective, but unfortunately, the fire detector works with a significant delay if the ignition source is not in close proximity to it. In addition, such systems have a high frequency of false positives. The most promising area for early fire detection is the use of computer vision based fire detection systemscomputer vision ba

In this paper, we present results from experiments that use the pattern and different analysis approaches to measure the dynamic range of a camera system as well as to describe the dependency of the SFR on object contrast and light intensity. The results can be used to improve the understanding of the performance of modern camera systems. These systems work adaptively and are scene aware but are not well des
