Claim 14:
15. A method for enhancing digital imagery, comprising:
receiving a linear, thermal image of an environment from one or more thermal cameras;
receiving a low-level light image of the environment from one or more low-level light cameras;
dividing the linear, thermal image into a plurality of tiles;
generating one or more histograms of intensity values for each set of pixels in each of the plurality of tiles;
based on the one or more histograms of intensity values, applying local contrast enhancement to the linear, thermal image to generate a contrast enhanced version of the linear, thermal image;
in parallel to applying the local contrast enhancement to the linear, intensity-based image, based on the one or more histograms of intensity values, applying artificial colorization to the linear, thermal image to generate an artificially colorized version of the linear, thermal image;
generating a composite image of the environment based on at least a portion of the contrast enhanced version of the linear, thermal image, at least a portion of the artificially colorized version of the linear, thermal image, and at least a portion of the low-level light image of the environment; and
overlaying the composite image of the environment in real-time for a user viewing the environment via a see-through display.
