Presence detection system

A presence detection system includes a camera that captures an image; an appearance-based detector that detects appearance of an object according to the image, thereby outputting an appearance-detection signal that is asserted when the appearance is detected; a proximity detector that detects motion...

Zusammenfassung:A presence detection system includes a camera that captures an image; an appearance-based detector that detects appearance of an object according to the image, thereby outputting an appearance-detection signal that is asserted when the appearance is detected; a proximity detector that detects motion of the object on a predetermined detection window on the image, thereby outputting a proximity-detection signal that is asserted when the motion is detected; and a fusion unit that receives the appearance-detection signal and the proximity-detection signal, thereby outputting an object-presence signal that is asserted when the appearance-detection signal or the proximity-detection signal is asserted.
