摘要
A system and method is provided for event detection for video surveillance systems (20) using a compressed prior image. Transform coefficients (125) for a current image are computed and compared to transform coefficients (145) representing the prior image. A determination is made whether a change has occurred sufficient to cause the detection of an event based on the results of the comparison.
