Complexity-Rate-Distortion Analysis of Backward Channel Aware Wyner-Ziv Video Coding
Many Wyner-Ziv video coding (WZVC) schemes encode a video sequence into two types of frames, key frames and Wyner-Ziv frames. We have previously presented a Wyner-Ziv video coding scheme that uses backward channel aware motion estimation to encode the key frames, where motion estimation was performed at the decoder and motion information was sent back to the encoder. We refer to these backward predictively coded frames as BP frames. In this paper, we extend our previous work and propose three types of motion estimators. A model is presented to examine the complexityrate-distortion performance of BP frames for the three motion estimators.
