ABSTRACT:
An image processor (10) is provided in which imaging data obtained by an image sensor (12) is processed for purposes of detecting motion. An optical flow field generator (16) processes the image data to provide condition number-based smoothed optical flow vectors, and stores those smoothed vectors in memory (18). The optical flow field stored in memory (18) is accessed and further processed by analyzer (20) for purposes of providing users with information on the motion of objects in the image plane of image sensor (12). Such user information may be displayed on a monitor (22).
