摘要 Abstract

A new paradigm for the design of video coding schemes that are suitable for wireless video and sensor network applications will be introduced in this talk. Conventional video encoding schemes like MPEG and H.26x are computationally intensive tasks and hence cannot be implemented in small, low-cost sensors. Low complexity video coding schemes that are based on distributed source coding techniques will be introduced. A (very) brief introduction to distributed source coding will be presented, and it will be shown how these techniques can be applied to video coding. After demonstrating the sub-optimality of one of the existing distributed video coding schemes, I will present our technique, namely, a hyper-trellis based Turbo decoding for Wyner-Ziv video coding.
