Abstract :
In this paper, a block-based coding scheme is proposed. Unlike those schemes exploited in a conventional codec, the proposed scheme takes the post-processing scheme to be used in the decoder into account during encoding. An example is also provided in this paper to show how this coding scheme jointly optimizes the compression and the blocking-effect elimination when an MPEG-4 deblocking filter is exploited in the post-processing stage
