Topology preservation is a necessary condition to be satisfied, especially for landmark-based image registration. Here, we focus on two different families of radial kernels, known as Gneiting and Matérn kernels. So, taking a number of landmarks, we analyze topology preservation and registration properties of these two families of kernels. Finally, we show some results considering test examples and real applications.
