The goal of this work is to seek a feasible direction of video coding that can provide a significant quality improvement over H.264. In light of the well-known findings that the distortion metric for video quality has a profound impact on video coding performance and that traditional metrics such as mean square error are poorly correlated with human perception, we identify perceptual video coding,...
The rate-distortion optimization (RDO) framework for video coding achieves a tradeoff between bit-rate and quality. However, objective distortion metrics such as mean squared error traditionally used in this framework are poorly correlated with perceptual quality. We address this issue by proposing an approach that incorporates the structural similarity index as a quality metric into the framework...
