Abstract

In this work we describe a study on a limited number of artifacts in MPEG-2 compressed video with the primary aim to analyze how annoying these compression artifacts are. More specifically, the objectives were: (1) to determine how the subjective annoyances of individual artifacts contribute to the overall annoyance, (2) to obtain the subjective ranks of the artifacts, and (3) to determine what relationships exist between annoyance values and annoyance ranks. To this end, a psychophysical experiment was carried out in which observers provided us with their subjective assessment of video sequences. The results showed that at low compression bit-rates, the blocking artifacts were the most annoying, whereas at higher compression bit-rates the ringing artifacts were the most annoying. The blocking artifact had the highest mean annoyance rank across all videos and compression bit-rates. Mean annoyance values were ordered differently from mean annoyance ranks due to very high annoyance values associated with some artifacts. Overall annoyance was related to the total squared error by a Logistic function. Individual artifact annoyance was related to overall annoyance by a weighted Minkowski metric.
