On Side Information Generation for Wyner-Ziv Video Coding

Distributed video coding (DVC) is a new video coding paradigm, which allows a reverse complexity codec in which the complexity is shifted from the encoder toward the decoder. Many DVC implementations have to make a prediction of the encoded frame at the decoder side using only the other frames as reference, in a process called side information (SI) generation. This process is crucial to any DVC framework a better SI will lead to a better rate distortion performance. In this work, we propose a linear motion mode to produce SI associated with, and a way to deal with the common problems of this model. Results are presented to support the proposed method.
