Abstract
In this paper we intend to present an original approach that incorporates shape prior into a geometric active contours. A Fourier-based shape alignment method is used to define prior knowledge from a given reference shape. At a first step, we propose an invariant shape prior with respect to some Euclidean transformations (translation, rotation, and scaling factor). Then, we generalize to the case of affine ones. In order to take into account the ...
