Surface-based registration with a particle filter

Abstract

We propose the use of a particle filter as a solution to the rigid shape-based registration problem commonly found in computer-assisted surgery. This approach is especially useful where there are only a few registration points corresponding to only a fraction of the surface model. Tests performed on patient models, with registration points collected during surgery, suggest that particle filters perform well and also provide novel quality measures to the surgeon. © Springer-Verlag Berlin Heidelberg 2004.
