Abstract: In this paper we propose the use of a local image transformation involving radial
basis functions for landmark-based registration of medical images. More precisely, we
consider radial basis functions as nodal functions in the modi ed Shepard method. In this
way we obtain an image transformation more accurate and stable than the one given by
the global radial basis functions, as shown by numerical results.
