Fuzzy regularisation of deformation fields in image registration

Antonio Tristán-Vega, Santiago Aja-Fernández.

We introduce the use of a variable smoothing kernel, whose width is driven by a fuzzy controller, to regularise a deformation field in the context of image registration. Our experiments show that such a technique outperforms the classical fixed-width regularisation, being capable of removing irregularities in the deformation field while maintaining an adequate adaptive behaviour for localised deformations, thus preserving fine details.
