Abstract
In this paper, we propose a method for non-rigid image registration based on a spatially adaptive stochastic model. A smoothness constraint is imposed on the deformation field between the two images which is assumed to be a random variable following a Gaussian distribution, conditioned on the observations and maximum a posteriori (MAP) estimation is… (More)
