Facial Recognition Thermal Images



Facial recognition in the dark
Facial recognition generally requires well-lit photos to make a match, but warfighters often need to identify individuals from images taken by thermal cameras in low-light or nighttime conditions. With the help of artificial intelligence, Scientists with the Army Research Lab have developed a way to enhance images from night-vision cameras so that they can be matched to conventional images in existing biometric face databases or watch lists.
The approach creates a visible facial image that has been synthesized from multiple regions of a thermal image. By combining features from the across the entire face with those of specific regions -- like the eyes, nose and mouth – the researchers were able to synthesize a refined visible image that could be run against a face database
Making a match between the visible and thermal image types required training a neural network to learn when the features from the two types of images were highly correlated, making it then possible for a matching system trained with visible imagery to be applied to thermal imagery.

This approach will allow the military to expand its facial recognition capabilities without developing custom software.
