Notes Comput. Sci. 2106, 389-397 (2001). 2001 Berlin: Springer EN Summary: We embed the minimization scheme of an automatic 3D non-rigid registration method in a multi-scale framework. The initial model formulation was expressed as a robust multiresolution and multigrid minimization scheme. At the finest level of the multiresolution pyramid, we introduce a focusing strategy from coarse-to-fine scales which leads to an improvement of the accuracy in the registration process. A focusing strategy has been tested for a linear and a nonlinear scale-space. Results on 3D Ultrasound images axe discussed.
