True color infrared photography and video
First Claim
1. A method of producing a true color image comprising the steps of:
- obtaining an infrared image of a scene over different spectral bands;
determining if an object within said image is identifiable;
segmenting said image into an object containing portion and a non-object containing portion if said object is identifiable;
comparing said object containing portion to a plurality of stored object feature characteristics;
coloring said object containing portion of said image according to information from said stored object feature characteristics if said object matches a set of said stored object feature characteristics;
determining if a pattern within said image is identifiable;
segmenting said image into a pattern containing portion and a non-pattern containing portion if said pattern is identifiable;
coloring said pattern containing portion of said image using multispectral imaging in conjunction with stored pattern information; and
coloring said non-object and non-pattern containing portions of said image by applying multispectral imaging to said image.

Abstract
A method beginning at (10) is provided for creating high-fidelity visible coloring from infrared images of a scene under surveillance. The infrared images captured at (12) are analyzed at (14) to determine if an object, such as a face, is identifiable within the image. If an object is identifiable at (16) the object features are compared to a plurality of stored object features at (20). If there is a match at (22), the color characteristics of the object are obtained at (24) and the object is colored at (26) based on the stored database feature information. If there is no match at (22) or identifiable object at (16) and object color cannot be identified at (23), the image is analyzed at (28) to determine if a pattern, such as clothing, is identifiable within the image. If a pattern is identifiable at (30), the color characteristics of the pattern are obtained at (34) and the pattern is colored at (36) according to infrared reflectance characterization in conjunction with the stored pattern information. If no pattern is identifiable at (30), the non-pattern and non-feature containing portions of the image are colored at (38) according to infrared reflectance characterization.

21. A method of producing a true color image comprising the steps of:
-
obtaining an infrared image of a scene over different spectral bands;
determining if an object within said image is identifiable;
segmenting said image into an object containing portion and a non-object containing portion when said object is identifiable;
