Abstract
A new side information generation algorithm using dynamic motion estimation and post processing is proposed for improved distributed video coding. Multiple reference frames are employed for motion estimation at the side information frame generation block of the decoder. After motion estimation and compensation, post processing is applied to improve the hole and overlapped areas on the reconstructed side information frame. The proposed side information method contributes to improve the quality of reconstructed frames at the distributed video decoder. The average encoding time of the distributed video coding is around 15% of H.264 inter coding and 40% of H.264 intra coding. The proposed side information based distributed video coding demonstrates improved performance compared with that of H.264 intra coding.
