초록
An efficient distributed video coding algorithm using symmetric motion estimation and channel division is proposed in this work. We employ the symmetric motion estimation to generate high quality side information for Wyner-Ziv frames. Also, in the channel division, we classify blocks in the side information into reliable ones and unreliable ones. Then, we transmit parity bits for unreliable blocks only, achieving a coding gain. Simulation results demonstrate that the proposed algorithm provides up to 4 dB better PSNR performance than the conventional distributed video coding algorithms. © 2009 IEEE.
