1. A method for identifying aberrations within an image comprising pixels, the method comprising: adjusting the image by applying a function to increase differences of intensity values of a plurality of pixels within the image; generating an error map based on a comparison of a first set of pixels within the image to a second set of pixels within a reference bitmap of the image; removing a third set of pixels from the error map based at least in part on user-input parameters; and generating a distortion map that identifies aberrations within the image, the distortion map being generated based at least in part on the error map, the image, and the reference bitmap of the image.
