Abstract :
In most current image/video coding systems, the compression stage and the restoration 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 contribution of the restoration to be performed can be taken into account in the compression by jointly optimizing the two processes. An example is also provided to show how this idea works successfully when MPEG-4 deblocking filter is exploited in the post-processing stage.
