METHOD AND APPARATUS FOR VIDEO QUALITY MEASUREMENT WITHOUT REFERENCE

摘要

This invention relates to video quality measurement without having the information of the original signal. The method for measuring video quality of a video received in a data stream comprises steps of extracting from the data stream low level stream information such as QP or bitrate, estimating video quality based on artefacts, comprising determining blur, determining blockiness and determining noise, and combining the low level stream information and the artefacts based estimated video quality, wherein a video quality measure is obtained.
