Spectrum shape elements model for correction of multichannel images

This paper presents the spectral-shape elements model for correction of non-isoplanatic deviation in the scene illumination. I propose an identification of the correction function on the set of spectral shape elements with the Hausdorff metric. Also a necessary condition which allows to obtain an adequate form of the color correction function is presented. The experiments performed on real images confirm the high quality of the proposed color correction technique with respect to well-known Retinex method.
