This paper presents a new method of non-rigid registration based on elastic models incorporating shape information. Given a source and a target image, and the shape of interest in these two images, the idea is to incorporate the geometrybased shape knowledge into extemal forces, which will drive the deformation from the source image to the target image. The transformations are constrained to a physical model of elasticity to maintain smoothness and continuity. Some experiments were performed on both synthetic and medical images of brain.
