ABSTRACT:
A method and apparatus for detecting cuts in a digital video signal made up of a series of video images is disclosed. The method comprises segmenting a plurality of the video images into a number of cells, each comprised of a number of pixels having a pixel intensity value. Then, a plurality of cell contrast vectors each associated with one of the segmented video images is generated. An element of the cell contrast vector comprises the standard deviation of the pixel intensity values for the pixels in a particular cell. A cut detect signal is generated for a video image in response to the cell contrast vector associated with that image.
