System and method for component discrimination enhancement based on multispectral addition imaging
First Claim
1. A method comprising:
- obtaining an optical image representative of a sample scene wherein said sample scene comprises at least one target material;
acquiring spectroscopic data representative of a first target material in said sample scene wherein said spectroscopic data comprises at least one spectrum representative of said first target material;
selecting a first spectroscopic band of interest and a second spectroscopic band of interest from said spectrum representative of said first target material;
obtaining a ratio of said first spectroscopic band of interest and said second spectroscopic band of interest;
comparing said ratio to a range of threshold values; and
based on said comparison, displaying a result wherein said result comprises a first pseudo color overlay on said optical image, and wherein said first pseudo color overly is obtained by assigning a first pseudo color to said first target material and wherein said first pseudo color corresponds to at least one of;
a known material and a class of known materials.

Abstract
A system and method for performing multispectral color addition imaging. An optical image is obtained for a sample scene comprising one or more target materials. Spectroscopic data is obtained for one or more target materials. A first and second waveband of interest are obtained for one or more target materials. A ratio of the first and second wavebands of interest is obtained and compared to one or more ranges of threshold values. Based on this comparison, a result is displayed wherein this result comprises a pseudo color overlay on said optical image. The pseudo color image may comprise one or more pseudo colors assigned to one or more target materials so as to differentiate and identify the target materials present in the sample scene.
