Inspired by recent advances in objective video quality assessment, this paper proposes a novel, local quantisation parameter (QP) determination approach for perceptual video compression, based on the experimental results of a QP selection test. This method has been fully integrated into the High Eciency Video Coding (HEVC) reference codec for intra coding, which predicts coding tree unit (CTU) level QPs to achieve optimised rate quality performance. The proposed approach consistently shows bitrate savings based on perceptual quality metrics and Bjontegaard delta measurements, with minimal complexity increase over the original codec.
