Wyner-Ziv video coding with region adaptive quantization and progressive channel noise modeling

In this paper, we propose a region-adaptive quantization scheme and progressive side information/channel noise modeling for Wyner-Ziv video coding. The proposed region-adaptive quantization scheme can enhance coding performance and provide an additional functionality of region of interest (ROI) coding. It also improves the accuracy of channel noise modeling by using previously decoded bit-plane information. Simulation results show that the proposed region-adaptive quantization scheme is especially suitable for static sequences, and the progressive side information/channel noise modeling works well in dynamic scenes.
