|---|---|---|
Distributed video coding (DVC) is one of the fastest growing coding techniques in the current signal processing world. It has its outstanding low complex encoder which is essential for some applications in the consumer market. Driven by the above motive, in this paper we propose a novel side information refinement technique for Wyner-Ziv video frames in DVC. When a bit plane is decoded, it is used to replace the corresponding bit plane in the side information and used for motion estimation and compensation to up date the side information. Then the information for the next bit plane is extracted from the updated side information and is sent to the turbo decoder as in a conventional DVC decoder. This process is repeated until all bit planes are extracted. This technique can be employed with almost all the side information generation techniques from simplest conventional pixel interpolation to advanced techniques such as bi-directional motion estimation and spatial motion smoothing (BiMESS) (8). Simulation results show that over 1.4dB PSNR gain can be obtained with the proposed algorithm over the BiMESS smoothing algorithm at the same bit rate. |
