VIDEO PROCESSING SYSTEM EMPLOYING BEHAVIOR SUBTRACTION BETWEEN REFERENCE AND OBSERVED VIDEO IMAGE SEQUENCES

摘要

An image processing method includes calculating sequences of motion labels from each of first and second sequences of images, each sequence of motion labels including motion label values indicating levels of motion activity in corresponding regions of the corresponding sequence of images. First and second behavior representations are calculated, each from the sequences of motion labels calculated from the respective image sequence, such that each region of each behavior representation represents a measure of motion activity of the corresponding region throughout the respective sequence of images. A comparing function of the first and second behavior representations is calculated, and an output signal is generated that reflects a result of calculating the comparing function. Applications include surveillance applications in which anomalous behavior is identified in an observed image sequence versus background behavior in a training image sequence.
