This paper presents an adaptive elastic deformation method, which decrease the bending energy and limit deformation regions at the same time. A new compact support radial basis function (CSTFP) is used to perform local elastic deformation. The optimal support radius of CSTPF is analyzed based on the distance between landmarks in theory. The interpolation function using CSTPF is controlled automatically...
Common tools based on landmarks in medical image elastic registration are Thin Plate Spline (TPS) and Compact Support Radial Basis Function (CSRBF). TPS forces the corresponding landmarks to exactly match each other and minimizes the bending energy of the whole image. However, in real application, such scheme would deform the image globally when deformation is only local. CSRBF needs manually determine...
