When a 2D image is displayed on a 3D (autostereoscopic) monitor, its resolution is significantly degraded. To overcome this problem, CityU developed an active barrier that converts a 2D display device into a 3D display device. The invention does not involve the design and development of the active b.....

To achieve the highest coding efficiency, H.264 uses rate distortion optimization technique to get the best coding result in terms of maximizing coding quality and minimizing bit rates. This means that the encoder has to code the video by exhaustively trying all the mode combinations including the d.....
