1. A method of denoising a plurality of pixels in a color digital image, the method comprising using a processor to perform the steps of: analyzing the plurality of pixels to identify those pixels having a high likelihood of containing significant noise; for each pixel having a high likelihood of containing significant noise, selecting nearby pixels having a lower likelihood of containing significant noise; and forcing each pixel having a high likelihood of containing significant noise to be photometrically coherent with the selected nearby pixels for that pixel having a lower likelihood of containing significant noise, wherein the forcing of each pixel comprises one of replacing each such pixel with its projection onto a line between two of the nearby pixels and replacing each such pixel with its projection onto a surface defined by at least three of the nearby pixels.
