题目 TITLE:多视点视频编码 ------Multiview video coding
时间TIME:2009年7月21日上午9:00 ------July 21st 9:00am
地点 ROOM:武汉光电国家实验室F401
报告人Speaker: 孙惠方博士Dr. Huifang Sun
报告摘要Report Abstract:
Conventional video coding systems are designed to encode the video from a single video source. With the emergence of new interactive applications and display technology that require multiple views of video, there is a need to extend the conventional coding schemes to exploit the redundancy between camera views and provide higher coding efficiency than independent coding of each view. Disparity compensated prediction is one of the more common techniques to exploit inter-view correlations. In this scheme, certain views are encoded independently using a standard video encoder; these independently encoded views are reference views. The remaining views are then encoded using temporal prediction and inter-view spatial predictions based on reconstructed reference views. The prediction can be etermined adaptively on a per block basis.
