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.
Claims31
A method for producing a color image in nighttime or low light conditions comprising:
- determining a spectral signature of an object in at least a portion of an input image;
- associating said spectral signature of said object with a color;
- and
- producing an output image having said color.
A system for producing a color image in nighttime or low light conditions comprising:
- a filtering element for dividing a received input image into a plurality of spectral components;
- a database for storing a plurality of predetermined spectral signatures and associated colors;
- and
- a processor for producing a color image having colors associated with said predetermined spectral signatures that correspond to said spectral components of said input image.
