A REDUCED REFERENCE VIDEO QUALITY METRIC FOR AVC/H.264

摘要

A reduced reference video quality metric for AVC/H.264 is proposed.This reduced reference metric evaluates a set of featuressuch as blur or blocking and combines these measurements intoone quality information using multivariate data analysis. The metricneeds a very low overhead in terms of additional bit rate and isverified with data from accurate subjective testing. It does not onlyoutperform standard PSNR but also shows to be superior comparedto two full reference video quality metrics. In addition a method fordesigning video quality metrics is presented. This method is basedon multivariate data analysis, a tool that is widely used in chemometrics and food science to predict latent variables such as taste byevaluating a set of variables that can easily be measured.
