Near-Infrared Assisted Eye Localization
Face recognition approaches often rely on accurate registration of the facial bounding box in an image. One approach is to align the images based on the location of the eyes. This project is an implementation based on the "bright eye effect" approach of Morimoto et al (2000). It involved hardware and software components. The hardware component involved the design of a simple circuit which switches betweeen two near-infrared (NIR) light sources in synchrony with the framegrabber of a Point Grey Flea firewire camera. The software component performed frame-differencing, thresholding and some simple heuristics to identify the most probable eye locations.
