Abstract
Image analysis is used for low light gaze detection in a vehicle environment. An infrared (IR) light source is sent toward an individual within a vehicular environment. IR light reflections are received from the individual by at least one video camera. At least one eye of the individual is obscured by a semitransparent material. Low accuracy tracking of the individual is evaluated using the IR light reflections through the semitransparent material. A signal-to-noise ratio for a sequence of video image frames is enhanced using the IR light reflections of the individual through the semitransparent material. Enhancing enables detection of feature points in an eye region for the individual. Eye location for the individual is determined based on results of the enhancing a signal-to-noise ratio. Real-time gaze direction of a pupil is derived for the at least one eye. The deriving is based on the determining the eye location.
