Abstract
A method and device for elastic registration of a two-dimensional source digital image of an object of interest with a slice of a three dimensional target volume of the object of interest is provided which defines a Markov Random Field framework having at least one undirected pairwise graph superimposed a two-dimensional image domain having at least a set of regular vertices and at least a set of edges, and defines a grid of control points, each control point corresponding to a vertex of the set of regular vertices, and a neighborhood system of edges associated with vertices. The method also defines a set of multi-dimensional labels of a discrete space to apply a displacement to each control point, the control point displacement defining a transformation adapted to obtain a plane slice of the target volume and an in-plane deformation transformation of the source digital image.
