CONTRAST AND VISIBILITY UNDER WINTER CONDITIONS WITH APPLICATION TO MOTION DETECTION SYSTEMS

Video motion detection systems are used to automate the detection of intruders for physical security purposes. Wintertime conditions of fog and falling or blowing snow are likely to hinder the detection of objects by either an observer or a motion detection system. Theoretical equations of contrast and visibility are reviewed.
