ABSTRACT:
A method and apparatus for compressing a dissolve region within a sequence of digital motion video frames. A function is calculated based on statistical data derived from frames in the sequence. Dissolve region boundaries are then detected based on characteristics of the calculated function. Consecutive detected boundaries may be flagged as a dissolve region based on the average value of the function between the consecutive detected boundaries and the distance between the consecutive detected boundaries.
