Abstract
Image matching of deformable structures has captured
great attention in image processing, and specially in the
medical field. This paper proposes a method that faces the illposed
nature of this problem, by using a cluster-sized
similarity cost function, the ambiguity in each similarity map
is described by a fuzzy parametric model, and, finally, a
spatially non-uniform fuzzy interpolation is used to translate
the parametric info into a set of matching field vectors. The
method obtains the spatial matching between the two images
in a global spatial extent and with sub-pixel accuracy. Results
of the method on real images and high non-rigid artificial
deformation proves the validity of the approach. Its extension
to a volumetric approach is also suggested.
