IN-LOOP BLOCK-BASED IMAGE RESHAPING IN HIGH DYNAMIC RANGE VIDEO CODING

摘要

Systems and methods are disclosed for in-loop, region-based, reshaping for the coding of high-dynamic range video. Using a high bit-depth buffer to store input data and previously decoded reference data, forward and backward, in-loop, reshaping functions allow video coding and decoding to be performed at a target bit depth lower than the input bit depth. Methods for the clustering of the reshaping functions to reduce data overhead are also presented.
