Abstract: A night vision coloring system may color a scene by extracting the spectral signature of each area in a scene and matching the extracted signature with a predetermined database signature and associated color. The system may comprise a temporal or spatial filtering element that may typically allow the capturing of an image reflection through a plurality of spectral bands, thereby extracting the spectral signature of each area in the image. The color associated with the matched database signature may be used to color each area comprising the image.

Abstract: A system for eye tracking that determines the line of sight of a user according to the relative position between the center of the pupil and a reference point, the system including an image detector that captures an image of the eye, a pupil-illuminating light source that illuminates the pupil of the user, a reference light source that illuminates a different portion of the face of the user as a reference point and an imaging processor that analyzes the captured eye image to determine the line of sight.
