Diffusion-snakes: combining statistical shape knowledge and image information in a variational framework
Daniel Cremers, Christoph Schnörr, Joachim Weickert · 2002
We present a modification of the Mumford-Shah functional and its cartoon limit which allows the incorporation of statistical shape knowledge in a single energy functional. We show segmentation results on artificial and real-world images with and without prior shape information. In the case of occlusion and strongly cluttered background the shape prior significantly improves segmentation. Finally we compare our results to those obtained by a level-set implementation of geodesic active contours.
