We propose an efficient polynomial time algorithm to match an elastically deforming shape to an image. It is based on finding a globally optimal geodesic in the product space spanned by the image and the prior contour. To this end a branch-and-bound scheme is combined with shortest path techniques.
We compare this algorithm with a recently proposed ratio minimization approach. While we show that generally the ratio is the better model, for many instances the two perform similarly. We identify a class of problems where the proposed method is likely to be faster.
