  • Confined motion detection for pan-tilt cameras employing motion detection and autonomous motion tracking
    Patent number: 9041800
    Abstract: A method of operating a surveillance system includes capturing a sequence of images of a field-of-view. A source of localized motion is disposed within at least one of a plurality of segments of the field-of-view. Provided to an operator is means to enable or disable, for at least one of the segments of the field-of-view, a localized motion identification and notification function wherein localized motion in the segment is automatically identified and distinguished from transient motion, and the operator is automatically notified about the presence of the localized motion.

  • Method of motion detection and autonomous motion tracking using dynamic sensitivity masks in a pan-tilt camera
    Patent number: 8189869
    Abstract: A method of identifying motion within a field of view includes capturing at least two sequential images within the field of view. Each of the images includes a respective array of pixel values. An array of difference values between corresponding ones of the pixel values in the sequential images is calculated. A sensitivity region map corresponding to the field of view is provided. The sensitivity region map includes a plurality of regions having different threshold values. A presence of motion is determined by comparing the difference values to corresponding ones of the threshold values.
