ABSTRACT:
There is provided a method of detecting dissolve/fade in an MPEG-compressed video environment, which includes the steps of: detecting a candidate sequence that is presumed to use a dissolve/fade editing effect according to shot transition detection in a video sequence; finding if spatio-temporal macro block type distribution that characteristically appears in a dissolve/fade sequence arises in the dissolve/fade candidate sequence, to judge if a scene transition by dissolve/fade was used in the detected dissolve/fade candidate sequence; and when the spatio-temporal macro block type distribution in the dissolve/fade sequence continuously appears in the dissolve/fade candidate sequence, comparing the length of the candidate sequence with a predetermined critical value and finally judging that the candidate sequence is a dissolve/fade sequence when its length is longer than the threshold.
