摘要

本文提出了一种计算视觉信号感知失真的新方法，旨在为典型移动多媒体通信中低比特率MPEG-4和H.26L编码的感知质量提供一种客观的度量方法。检测具有三种主要感知干扰伪影的区域，即边缘破损、阻塞和环形，作为评估的基础。通过低比特率(24/spl sim/384 Kbps)的CIF和QCIF测试数据，证明了度量与人类感知的相关性。

Quality evaluation of MPEG-4 and H.26L coded video for mobile multimedia communications

This paper proposes a new approach for computing perceptual distortion for visual signal in order to provide an objective measure for perceptual quality at low bit rate MPEG-4 and H.26L coding in typically mobile multimedia communications. The regions with three major perceptually disturbing artefacts, namely, damaged edge, blockiness and ringing, are detected as the basis of assessment. The correlation of the metric with human perception has been demonstrated with low bit rate (24/spl sim/384 Kbps) CIF and QCIF test data.
