Image registration is the process of warping an image to increase its similarity to a second image. It has applications in medical imaging, where it is used to reduce natural variability in medical images. We explore landmark image registration. Given a model of the bending energy of an image and a group of fixed landmarks, there is a neat formulation to this problem as a two-point boundary value problem for a Hamiltonian system of differential equations. We explore the difficulties of registering images when the landmarks are uncertain. This involves developing a system of Langevin equations and sampling diffusion bridges.
