摘要：
In This paper, we proposed a new- video coding scheme based on four improvements. (1)Half pixel precision is used for the overlapped motion compensation. (2)Region wavelet decomposition is only applied to the significant region in prediction error image(DFD). (3)Zerotree is used for representation of the significant region wavelet coefficients. (4)A quantization model based on the HVS have been used for intraframe coding. Simulation results shown that some coding gain has been reached comparing to conventional wavelet coder.
