摘要
A picture quality assessment method based upon spatial location within the picture divides the video picture into a plurality of arbitrarily sized, geometric segments. A segment weighting map is generated that provides a low threshold for "safe picture" segments of the video picture and a high threshold for the other segments. The video picture on a segment basis is compared with a corresponding test video picture to generate a quality error value for each segment. On an error display the error value is displayed only where it equals or exceeds the threshold value from the segment weighting map.
