Temporal visual masking for HEVC/H.265 perceptual optimization

We present a method that employs human visual system characteristics for perceptually lossless optimization of video coding. Algorithm is robust and applicable for any modern hybrid coder. We decided to evaluate it using the most recent standard (HEVC/H.265) in order to show potential benefits for future applications. Experiments show savings of up to 8% in bitrate without any loss in quality as confirmed by two sets of subjective experiments using DSCQS and ACJ methodology.
