Abstract
A movement detection method and system capable of detecting picture point movement in portions of a picture in the presence of noise. Each picture point within the frame in turn is examined with a corresponding picture point from the previous frame to detect when movement has occurred for that particular picture point. To distinguish between noise and movement, a number of selected picture points adjacent the picture point are also examined to see if movement is occurring. By examining a number of picture joints noise tends to be attenuated while movement is not, so that true movement can be detected.
