1. A method for enhancing digital images, comprising:

  • accessing an input image comprising a background and a foreground;

    determining, by at least one processor, modifications to enhance the input image by minimizing an energy heuristic comprising a sum of a background parameter and a foreground parameter, wherein;

    the background parameter causes background pixels of the input image to change to a uniform color; and

    the foreground parameter preserves gradients of foreground pixels from the input image; and

    generating, by the at least one processor, an output image with an enhanced foreground by applying the determined modifications to the input image.
