In this paper. we propose an image qualiy iiteasure thor closely reseritbles the image qualiv measure used by the human visual sysiem. I n ourapplicotion. we are tiore concerned with localized errors due to trammission than the global errors due to conipression. a id we develop an approach that is appropriate for this purpose. We use psychophysicnl experiments to derennine the r,iribility rltre...

The multiview video exploits both texture and depth video information from various angles to create a 3D video [1]-[3] and free viewpoint video (FVV) [4] which are gradually becoming more popular for their advanced visual experience with depth perception [5]-[7]. Unlike texture, depth video is determined by a gray scale map indicating distance between camera and 3D points in a scene [8]. If a c...

This study used the complex dynamic characteristics of chaotic systems and Bluetooth to explore the topic of wireless chaotic communication secrecy and develop a communication security system. The PID controller for chaos synchronization control was applied, and the optimum parameters of this PID controller were obtained using a Particle Swarm Optimization (PSO) algorithm. Bluetooth was used to...

In this paper, an enhancement design of communication system using optical radio frequency (RF) waves in free space optical communication (FSO) system is presented. To our knowledge, it is the first time that the effect of Gamma-Gamma turbulent channel model on the performance of the proposed system is analyzed and simulated. To obtain an optical communication system with good performance and h...

In the early stage of planning or design, it is desired to support the informal communication between remote sites. In this study, informal communication environment between remote places was constructed by using the interactive tiled display wall. This system measures the user's gesture as well as captures the user's image by using the multiple fish-eye cameras. Then, the remote users can comm...
