ABSTRACT:
A system detects scene changes in a sequence of video images by analyzing the sequence for abrupt frame-to-frame changes in certain image features. The system accepts the signal into a quantizer, which digitizes the image, and stores it into a frame buffer. An image processor, a component of the system, analyzes the digitized images, and determines certain features which a decision processor can use to detect a scene change.
