Abstract
A method for assessing the quality of a distorted version of a frame sequence includes the steps of determining a last spatial distortion by comparing a block of a last frame (I6) of the sequence with a corresponding block of the distorted version of the last frame, determining, in a last-but-one frame, a best-matching block matching said block of the last frame best, determining a last-but-one spatial distortion by comparing the determined best-matching block of the last-but-one frame with a corresponding block of the distorted version of the last-but-one frame, determining a spatio-temporal perceptual distortion value associated with said block using said determined distortions and using the determined spatio-temporal perceptual distortion value for assessing the quality.
