  2. Using the above algorithms, h. 263 baseline video - encoder implementation can encode more than 40fps in qcif resolution on a pentium mmx 500 - mhz computer. almost ali of the low bit - rate video compression techniques degrade quality. to combine the video quality evaluation with hvs, the relationship betvveen the motion activity and perceptual video quality are studied, and a video quality evaluation method based on motion activity is proposed, in which video defmition and smoothness are defined

    本文提出一種基於運動特徵的視頻質量評價方法，考慮了人眼對視頻信號感受質量與畫面運動劇烈程度之間的關系，分別討論了反映視頻質量的視頻清晰度和流暢度，評價結果更符合人眼視覺特性，並且這種評價對編碼具有一定的指導作用。
