Paper Abstract

In image local elastic transformation, compact support radial basis functions are used to implement image elastic deformation. The elastic deformation area is related to the support of the radial basis function. However, how to choose the support based on space distribution of landmarks still is an unresolved problem. In this paper, the relation between the support and three landmarks space locations is analyzed using simple triangle structure for Wendland radial basis function. Moreover, for landmarks set, Delaunay triangle is constructed to obtain the support of each triangle, and the optimal support of radial basis function is chosen as the maximum. Experiments of artificial images and medial images show the feasibility of our conclusions.
