In this paper a framework for a formal definition and a theoretical study of the change vector analysis (CVA) technique is proposed. This framework, which is based on the representation of the CVA in polar coordinates, aims at: (i) introducing formal definitions in the polar domain for a better general description and understanding of the information present in spectral change vectors; (ii) analyzing from a theoretical point of view the distributions of changed and unchanged pixels in the polar… CONTINUE READING
