ABSTRACT
We present a new way of constraining the evolution of a region-based active contour with respect to a reference shape. Minimizing a shape prior, defined as a distance between shape descriptors based on the Legendre moments of the characteristic function, leads to a geometric flow that can be used with benefits in a two-class segmentation application. The shape model includes intrinsic invariance with regard to pose and affine deformations.
INDEX TERMS
Segmentation, active contours, region-based approach, Legendre moments, shape constraint, shape derivative, affine invariance.
