HDR/WCG 영상 부호화를 위한 밝기-색상 분리 프레임워크

A Orthogonal color space transformation, CIECAM02, based framework for HDR/WCG video coding is proposed. The proposed framework provides transfer function to avoid banding artifacts caused by quantization, as well as orthogonal color space transformation. The experimental results showed that the proposed framework reduces visual artifacts occurred in the conventional framework.
