Title
A Novel Chroma Representation For Improved Hdr Video Compression Efficiency Using The Hevc Standard
Abstract
The human visual system's sensitivity to changes in colors varies based on the perceived color. In this work, we propose a chroma processing scheme that assigns more code-words to colors that our eyes are most sensitive to, so that perceived color differences generated by the quantization processes in the HDR video delivery pipeline are reduced. Performance evaluations showed that the proposed method significantly reduces the number of pixels with visible color differences as well as the mean error of the frames when compared to the original method. The proposed scheme improves the compression efficiency of the existing 10-bit Y'CbCr by an average of 8.16% and 30.36%, in terms of tPSNR-XYZ and DE100, respectively. The proposed scheme is easily implementable in hardware and can be interpreted by the current HEVC video coding standard using existing supplemental enhancement information (SEI) messages.
