CONTRAST ENHANCED IMAGES COMPOSITED WITH ARTIFICIAL COLORIZATION

Abstract:

A method for enhancing digital imagery. The method comprises receiving a linear, intensity-based image of an environment. A histogram of intensity values is generated for a plurality of pixels within the linear, intensity-based image. Based on the histogram of intensity values, local contrast enhancement is applied to the linear, intensity-based image to generate a contrast enhanced version of the linear, intensity-based image, and artificial colorization is applied to the linear, intensity-based image to generate an artificially colorized version of the linear, intensity-based image. A composite image of the environment is then generated based on at least a portion of the contrast enhanced version of the linear, intensity-based image and at least a portion of the artificially colorized version of the linear, intensity-based image.
