摘要

传统的MPEG-2视频压缩采用测试模型5 (TM5)作为速率控制算法，没有考虑压缩序列的感知质量。本文提出了一种新的速率控制算法，该算法将TM5与沃森的数字视频质量(DVQ)度量相结合。作为VQEG(视频质量专家组)的支持者，沃森的DVQ是一种基于人类视觉系统(HVS)的主观质量度量，它估计了人类观众的感知质量。仿真结果表明，该算法对低运动视频序列的性能优于TM5，对高运动视频序列的性能与TM5相当。

Subjective-quality-based MPEG-2 video compression

Traditional MPEG-2 video compression uses test model 5 (TM5) as the rate-control algorithm, which does not consider the perceptual quality of the compressed sequence. This paper proposes a new rate-control algorithm, which integrates TM5 with the Watson's digital-video-quality (DVQ) metric. As a proponent of the VQEG (Video Quality Expert Group), the Watson's DVQ is a subjective quality metric based on the human visual system (HVS) which estimates the perceptual quality of human viewers. Simulation results indicate that the proposed algorithm outperforms TM5 for low-motion video sequence, and performs about the same as TM5 for high-motion video sequences.
