【 摘 要 】

References(7)Cited-By(1)An efficient hybrid distributed video coding (HDVC) scheme combining residual coding, SW-SPIHT coding and intra-mode decision technology is proposed to offer good rate-distortion performance and low-complexity encoding. The scheme adopts the wavelet-domain Wyner-Ziv codec to compress the residual frame between the current frame and its reference frame. An intra-mode decision based on the temporal and spatial correlation is made to determine whether a wavelet block is better coded or not. When the estimated correlation is weak, we use intra-SPIHT coding; otherwise SW-SPIHT(Slepian-Wolf SPIHT) coding is adopted. Experimental results indicate the proposed HDVC achieves evident improvement than the referenced.
