Deep neural networks for face recognition in darkness

Karlsruhe Institute of Technology researchers have used the heat from one’s face to enable facial recognition in darkness. Thermal imaging creates an infrared picture, which can then be matched to a photograph taken in the light.

In a recent study, a “deep neural network” accurately identified faces in the dark 80 percent of the time when shown a large number of photos.  However,  the technology is at an early stage, and was only successful 55 percent of the time when presented with a single  image.
