Description
Summary:This paper describes a new method to enhance the picture quality of digital video using coding information from the MPEG-2 bitstream. Experimental results show significant improvements with respect to traditional algorithms for video sequences containing coding artifacts. The proposed method can be adapted to various video enhancement algorithms (e.g. sharpness enhancement as presented in this paper) as well as to different coding standards (e.g. MPEG-4). Consequently, the proposed enhancement method can be incorporated into future digital video products (e.g. DVD, set- top boxes, digital TVs, etc) in order to achieve superior picture quality for encoded video.
