ABSTRACT:
Edge detector techniques, known per se in the art, are applied to the field of automated video quality assessment. Any known edge detection algorithm is used as the basis of an edge detection stage for performing edge analysis of test video fields/frames in order to generate an edge parameter value that can then be used to contribute to an overall video quality value. The use of an edge detector stage contributes valuable information concerning image attributes which are perceptually significant to a human viewer to the quality assessment, thus rendering the result provided by the automated assessment more similar to that which would be performed by a human viewer undertaking a subjective assessment.
