ABSTRACT:
A method of estimating a shot boundary in a digital video sequence comprises calculating a measurement of dissimilarity between each frame in the video sequence and its previous frame based on at least one of de-emphasized luminance differences and absolute color differences. Each frame is tested against shot boundary dissimilarity thresholds using the dissimilarity measurement for the frame thereby to detect the shot boundary.
