Abstract: Measurements that quantify perceptual video attributes in both the spatial and temporal domains are extracted from the video that has undergone digital coding and compression. These measurements are then used to compute a single score that quantifies the perceptual impact of the impairments present in the video sequence. This objective score is well-correlated (r=.92) with impairment assessments made by human viewers. A collection of 36 video scenes with a wide range of spatial and temporal complexity were passed through 28 video systems covering the range of compression from 45 Mbs/sec to 56 kbs/sec, including bit errors introduced into the digital transmission channel.
