A unified metric for digital video processing and its applications in home video systems

Abstract

MPEG-2 encoded video is widely used in digital home scenarios. To achieve better performance for MPEG sources, we propose a unified metric for digital video processing, UMDVP. The UMDVP is based on coding information and it also takes the local scene content into account. We have integrated the UMDVP with postprocessing functions such as resolution enhancement and artifact reduction. Experimental results demonstrate the benefit of the proposed metric. Various digital video products can use the new approach to achieve better performance for compressed video.
