  • Event detection for video surveillance systems using transform coefficients of compressed images
    Publication number: 20040086152
    Abstract: A system and method is provided for event detection for video surveillance systems using a compressed prior image. Transform coefficients for a current image are computed and compared to transform coefficients 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.
