Abstract
An object detection portal wherein a video image is obtained of a volume or area being scanned, and location of a threat object is determined and displayed in real time as an indicator overlay on the video image. An individual subject being scanned may be continuously monitored by an operator during an object divesting process, and an operator may view the threat object moving from or remaining with the subject. Object location information is supplied to a video driver to superimpose the overlay on a real time image of a subject. The scanning portal may interact with an exit barrier. The exit barrier may be activated automatically in response to sensing of a threat.
