Introduction: Video games affect the stress system and cognitive abilities in different ways. Here, we evaluated electrophysiological and biochemical indicators of stress and assessed their effects on cognition and behavioral indexes after playing a scary video game. Methods: Thirty volunteers were recruited into two groups as control and experimental. The saliva and blood samples were collect...

Many video processing algorithms rely on optical flow to register different frames within a sequence. However, a precise estimation of optical flow is often neither tractable nor optimal for a particular task. In this paper, we propose taskoriented flow (TOFlow), a flow representation tailored for specific video processing tasks. We design a neural network with a motion estimation component and...

Design of video processing circuits requires a variety of tools and knowledge, and it is difficult to find the right combination of tools for an efficient design process, specifically when considering open tools for evaluation or educational purpose. This chapter presents an overview of video processing requirements, programmable devices used for embed‐ ded video processing and the components o...

This paper discusses the programmable and dedicated approaches for real-time video processing applications. Various VLSI architecture including the design examples of both approaches are reviewed. Finally, discussions of several practical designs in real-time video processing applications are then considered in VLSI architectures to provide significant guidelines to VLSI designers for any furth...

Network-based computing is becoming an increasingly important area of research, whereby computational elements within a distributed infrastructure process/enhance the data that traverses through its path. We refer to these computations as online processing and this paper investigates scene change detection in the context of MBonebased proxies in the network. On-line processing varies from tradi...

There are numerous video processing algorithms and modules available. When the algorithms are not optimally tuned, undesired results may happen in the processed video signals, e.g. blurring, overshoots/downshoots, loss of details and aliasing. When the video processing modules are fixed, e.g. when the modules are implemented in hardware/chips, it is highly desirable to repair those unpleasant e...

In this paper, we study the problems of video processing in video search engine. Video has now become a very important kind of data in Internet; while searching for video is still a challenging task due to the inner properties of video: requiring enormous storage space, being independent, expressing information hiddenly. To handle the properties of video more effectively, in this paper, we prop...

Real-time video processing, such as rendering and/or encoding, is one of the most bandwidth demanding operation in audio-visual applications [1][2]. There have been many efforts at parallelizing video rendering and encoding architecture mainly for VLSI chip design [3][4][5][6][7][8][9][10][11][12][13] [14][15][16]. However, not a lot of research has been dedicated in the area of distributed com...

introduction: laryngeal dysfunction may be divided into three categories; organic, neurologic and functional disorders. dysphonia and hoarseness are the most common symptoms and, in some cases, the only signs of laryngeal dysfunction. in differential diagnosis of any type of chronic hoarseness, a neoplastic process must be considered and, thus continuous light video laryngoscopy can provide imp...
