AF prototypes skin-sensing camera

Researchers have developed an advanced sensing system that could better identify humans in surveillance videos or search and rescue operations by differentiating human skin from other materials in images.

Typical color-image based systems have high false detection rates, but the prototype camera system developed by the Sensors Exploitation Research Group at the Air Force Institute of Technology uses a skin detection and color estimation approach that is more accurate and requires only a small number of spectral channels, Air Force officials said.

The system can assess skin color in real time by detecting the amount of melanin and water in skin,  enabling it to differentiate between human skin and other materials — such as grass, trees or buildings —  and to simultaneously filter out skin colors that are not of interest.
