SYSTEM FOR AND METHOD OF SHARPNESS ENHANCEMENT FOR CODED DIGITAL VIDEO |
摘要 |
<p>A method and system for calculating a UME for each pixel in a frame of video data. A system for enhancing sharpness of a coded digital video signal representative a frame of block-based data is provided, comprising: a system for calculating a UME of each pixel in the frame in accordance with a frame type, wherein the calculating system includes: a mechanism that defines local spatial features in the frame; a mechanism that analyzes block-based motion estimation for the frame; a mechanism that detects a scene change in the frame; and a sharpness enhancer that improves sharpness to a decoded version of the digital video signal based on said UME.</p> |
