Rigid, affine and locally affine registration of free-form surfaces

A new framework to perform nonrigid surface registration is proposed. It is based on various extensions of an iterative algorithm recently presented by several researchers to rigidly register surfaces represented by a set of 3D points, when a prior estimate of the displacement is available. The fram...

Description
Summary:A new framework to perform nonrigid surface registration is proposed. It is based on various extensions of an iterative algorithm recently presented by several researchers to rigidly register surfaces represented by a set of 3D points, when a prior estimate of the displacement is available. The framework consists of three stages: search for the best rigid displacement to superpose the two surfaces; search for the best affine transformation; and local deformation of the surface. All these stages are illustrated with experiments on various real biomedical surfaces, which demonstrate the validity of the approach.
