SYSTEM AND METHOD FOR FLATNESS DETECTION FOR DISPLAY STREAM COMPRESSION (DSC)

摘要

A system and method for flatness detection for display stream compression (DSC) is disclosed. In one aspect, the method includes determining a first complexity value for a previous block of video data, a second complexity value for a current block of the video data, and a third complexity value for a next block of the video data. The method also includes determining whether the current block includes a transition from a complex region to a flat region based at least in part on the first, second, and third complexity values.
