A no-reference video quality evaluation method based on HEVC bitstream

摘要

In this paper, we propose a no-reference video quality evaluation method based on HEVC bitstream. The method extracts feathers from HEVC bitstream to estimate quality of the video. We choose Quantization Parameter Average (QPavg) and Skip Coding Unit Percent (Skip%) as features, PSNR as objective video quality evaluation method, and use linear regression to get the evaluation model. Experiment result shows that the method can accurately predict the objective quality of HEVC encoded video.
