Abstract
A multi-resolution representation is generated of at least one color component of a color image in a selected color space by applying a decomposition procedure to the color component. The multi-resolution representation(s) is (are) modified by application of at least one non-linear modifying function. Next, modified color component images are generated by applying the inverse of the decomposition step to the modified multi-resolution representations(s).
