Subjective Video Quality
The main goal of many objective video quality metrics is to automatically estimate average user (viewer) opinion on a quality of video processed by the system. Sometimes however, measurement of subjective video quality can also be challenging because it may require a trained expert to judge it. Many “subjective video quality measurements” are described in ITU-T recommendation BT.500. Their main idea is the same as in Mean Opinion Score for audio: video sequences are shown to the group of viewers and then their opinion is recorded and averaged to evaluate the quality of each video sequence. However, details of testing may vary greatly.

Famous quotes containing the words subjective, video and/or quality:
“... the subjective viewpoint is the only one to use regarding a library. Your true library is a collection of the books you want. You may have deplorably poor taste or bad judgment. Never mind. Correct those traits before you exchange your books.”
—Carolyn Wells (1862–1942)
“These people figured video was the Lord’s preferred means of communicating, the screen itself a kind of perpetually burning bush. “He’s in the de-tails,” Sublett had said once. “You gotta watch for Him close.””
—William Gibson (b. 1948)
“We’re headed for collapse, if you want my opinion, Missy. I can see it in the fallin’ off of the quality of vagrants. There was a time you could find real good company in almost any jungle you’d pick, men who could talk, men who’d read a book now and then; and now, what do you find, a lot of dirty little guttersnipes no decent tramp would want to associate with.
Well, it’s been that way all through history.”
—John Dos Passos (1896–1970)
