CORRECTION OF IMAGE COLOR LEVELS

摘要

Provided is a computer system and method for processing images. A method for applying a color bias correction for an image includes but is not limited to, separating high frequency data from low frequency data of the image: using the high frequency data to determine one or more local minima; applying a function of the local minima to determine a black level; using the high frequency data to determine one or more local maxima; applying a function of the local maxima to determine a white level; and correcting the color bias of the image by linearly interpolating the image between one or more values associated with the white level and one or more values associated with the black level.
