Presented herein are a system and method for sharpening edges in a region. In one embodiment, there is presented a method for sharpening edges. The method comprises measuring differences between at least a value associated with a first pixel and a value associated with a second pixel of a plurality of pixels, and applying a sharpening mask to the plurality of pixels. The sharpening mask is a function of at least one of the measured differences, a first value associated with any one of the plurality of pixels, and a second value associated with any other of the pixels, thereby resulting in sharpened pixels.
