Abstract :
A joint approach of resolution enhancement and artifact reduction for MPEG-2 encoded video is proposed in this paper. This new method uses a unified metric for digital video processing (UMDVP). The UMDVP is defined based on the coding information of MPEG-2 encoded video. It also takes the local scene content into account. Experimental results have demonstrated that the joint approach using the UMDVP outperforms the system of resolution enhancement and artifact reduction without the help of UMDVP. The proposed method can improve the performance of various emerging video systems using MPEG-2 compression.
