Pipelines for HDR Video Coding Based on Luminance Independent Chromaticity Preprocessing.
IEEE Transactions on Circuits and Systems for Video Technology（2018）
摘要
We consider the chromaticity in high dynamic range (HDR) video coding and show the advantages of a constant luminance color space for encoding. For this, we introduce two constant luminance HDR video coding pipelines, which convert the source video to linear Yu'v'. A content dependent scaling of the chromaticity components serves as color quality parameter. This reduces perceivable color artifacts...
