EXTENDING MATHEMATICAL MORPHOLOGY TO COLOR IMAGE PROCESSING

This paper addresses the problem of the extension of morphological operators to the case of color images. Two main strategies are proposed: the marginal strategy and the vectorial one, which basically comes to the definition of a well suited vector ordering relation. We briefly discuss the possible extensions found in the literature and propose an ordering scheme based on the bit mixing paradigm. Results concerning the different extensions of basic morphological operators are presented and compared.
