Hongyuan Fang · Radio & TV Broadcast Engineering · 1993
The method for the subjective assessment of quality of the TV Picture recommed by CCIR (Rocommendation 500-Ⅰ) is used commonly. But here, this paper intruduce sanew instrument to measuring and analyzing the vidio-noise and assessing the quality of TV pictures. This paper also discribes how to use the method of noise-shift to dispose an active-image-noise in ditail and other various methods, such as TV image noise autocorrelation analysis, power spectrum estimation and so on, to simulaty a subjective assessment result. This system has a simple interface. All functions above were performed on a micro-computer—IBM-PC/XT.
