ABSTRACT:
A passive skin detection system includes a main body which houses a collection optics system having an image splitting device, a visible light filter mechanism having a plurality of narrow band filters and an image capture system. The image capture system stores visible light data as a plurality of digital images formed from a plurality of pixels. Each of the plurality of digital images is associated with visible light passed through a respective one of the plurality of narrow band filters. An image processing system, operatively connected to the image capture system, compares relative intensities of each of the plurality of digital images to identify one or more of the plurality of pixels having an absorption bandwidth indicating a presence of skin. The processing system determines whether a person, identified by his skin, is present in any of the images captured by the detection system.
