In this paper, a perceptual video coding system is developed based on the newest coding standard-HEVC/H.265. We propote a local Just-Noticeable-Difference (JND) model, which simultaneously considers the contrast sensitivity model, luminance masking, temporal masking, residue-dependent adjustment, and the summation effect of quantization distortion to get the weighting of importance of human eye perception...
A frame-level bit allocation optimization method is proposed to improve the rate–distortion performance for High Efficiency Video Coding. First, to avoid the demerits of the mixture Laplacian distribution model on complexity, a new synthesized Laplacian distribution (SynLD) model is proposed to describe the discrete cosine transform transformed coefficients based on Kullback–Leibler-divergence analysis...
