A method may include the steps of segmenting an image into a plurality of tiles, calculating an upper clip limit and a lower clip limit for each tile of the plurality of tiles based upon a user input standard deviation, generating a lookup table for each tile of the plurality of tiles by linearly mapping the pixels of the image based upon the calculated upper clip limit and lower clip limit, processing each tile of the plurality of tiles based upon the generated lookup table, and generating a processed image by combining each of the processed tiles. The method may include the steps of scaling the image between zero and one and/or scaling the image based upon the display type. The method may be stored on a computer readable medium and may be used in an image processing system having memory, a processor, and a display.
