APPARATUS AND METHOD FOR PROVIDING A USEFULNESS METRIC BASED ON CODING INFORMATION FOR VIDEO ENHANCEMENT |
摘要 |
<p>An apparatus and method for enhancing the quality of a digital video signal uses coding information for use in connection with spatial domain sharpness enhancement algorithms used in multimedia devices. The sharpness of previously encoded or transcoded digital video images is enhanced without enhancing encoding artifacts. The apparatus includes a usefulness metric generator that identifies a limit to the sharpness enhancement of an image that can be applied to a previously coded digital video that represents a sequence of images without enhancing coding artifacts. The usefulness metric generator applies the usefulness metric to at least one sharpness enhancement algorithm. The usefulness metric and the sharpness enhancement algorithm are separate so that the usefulness metric can be used with a variety of video enhancement algorithms.</p> |
