The detection of motion from image sequences is usually performed using a time differential method or calculating the difference from a background reference image. These algorithms often perform poorly in the presence of temporal clutter. This paper describes a technique that measures the irregularity of an intensity sequence to detect motion. We(More)
A motion detection technique is presented which exhibits robust properties suitable for general operation in a surveillance environment. The technique is sensitive to transient perturbations present in an image sequence while being insensitive to temporal clutter. Its performance is robust to scale and ooset variations in the input sequence. The system is(More)
