Abstract
A novel SSIM based RDO approach for intra-only coding in HEVC is presented. We incorporate SSIM into the distortion measure for variable size CTUs. The corresponding Lagrange multiplier is also derived. The experimental results show that the proposed RDO approach achieves 8.54% bit-rate reduction on average.
