Objective quality assessment of digitally transmitted video

摘要: The authors discuss an automated, objective video quality measurement system being developed for use in measuring end-to-end user performance. method is based on extraction and classification of features from sampled input output video. extracted quantify many the distortions present modern digital compression transmission systems. These include artifacts resulting spatial (blocking, edge blurring/smearing, etc.) temporal (image persistence, jerky motion, etc.). Since motion still portions a scene can differ dramatically, algorithm that segments each frame into parts has been developed. >
