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.
