Abstract: In most current block-based image/video coding systems, the compression stage and the deblocking stage operate separately and hence they cannot make use of each other to optimize the overall coding performance. In this research, we suggest modifying the basic structure of the encoding systems such that the deblocking to be performed can be taken into account m the compression by jointly optimizing the two processes. Examples are also provided to show how this idea works successfully in an MPEG-4 coder and a H.263 coder to boost the rate-distortion performance when the suggested optimized deblocking filters are exploited in the post-processing stage.
