Abstract
A system for processing a multiband image, including digital computer memory for storing a multiband image having multiple bands of image data; and processing circuitry for processing the multiband image, wherein the processing circuitry (a) determines pixel locations in the bands of the multiband image having values above the band-specific white value threshold for each of the bands of the multiband image, (b) determines a band-specific correction factor for each of plural bands of the multiband image based on the determined pixel locations, and (c) applies the corresponding band-specific correction factor to the respective plural bands of the multiband image to produce a corrected image.
