12-3 HEVC符号化映像のNo Reference型客観評価に関する検討(第12部門[テーマ講演]HVEC符号化)

抄録

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.
