Claim One:
1. A method for outlier detection for color mapping, the method comprising: retrieving a reference image and a test image; determining a set of pairs of corresponding feature points between the reference image and the test image, for each pair of the determined set there is a feature point in the reference image and a corresponding feature point in the test image; determining an initial color mapping model for each pair of corresponding feature points between the test image and the reference image; applying the initial color mapping model to the test image to generate an initial color-corrected test image; for each pair of corresponding feature points of the determined set of pairs, comparing color values of a spatial area around the feature point in the reference image with color values of a spatial area around the corresponding feature point the initial color-corrected test image; when said comparison of color values related to a given pair of corresponding feature points meets a threshold criteria, deleting the given pair of corresponding feature points to generate a reduced set of pairs of corresponding feature points; and processing the reduced set of corresponding feature points for transmission to a signal processor.
