Abstract

In this paper we propose a new deringing algorithm for MPEG-2 encoded video. It is based on a Unified Metric for Digital Video Processing (UMDVP) and therefore directly linked to the coding characteristics of the decoded video. Experiments carried out on various video sequences have shown noticeable improvement in picture quality and the proposed algorithm outperforms the deringing algorithm described in the MPEG-4 video standard. Coding artifacts, particularly ringing artifacts, are especially annoying on large high-resolution displays. To prevent the enlargement and enhancement of the ringing artifacts, we have applied the proposed deringing algorithm prior to resolution enhancement. Experiments have shown that in this configuration, the new deringing algorithm has significant positive impact on picture quality.
