12-3 Study on objective no reference metric of perceived quality of the pictures coded by HEVC

Abstract

We propose an objective video quality metric based on Hybrid NR framework to evaluate the pictures coded by HEVC. The proposed metric extracts three image features to estimate subjective quality: QP from the compressed bitstream and blockiness and flickering features from the decoded pictures. Computer simulations show that the proposed metric can estimate the MOS of HEVC-coded sequences at a correlation coefficient of 0.86.
