Abstract
This paper presents an algorithm for the reconstruction of digital color image component signals corrupted by impulse noise by exploiting interchannel redundancy. Results of numerical studies have shown that intercomponent gradient reconstruction is superior to median filtering in the accuracy of reconstruction of lost or corrupted color image elements. Processing of a three-component digital color image has shown the efficiency of the proposed algorithm.
