Multiscale extraction of features from medical images

Part of the Lecture Notes in Computer Science book series (LNCS, volume 970)


We present a fast and reliable algorithm, based on iso-surface techniques, to extract differential invariant features at increasing scales. We show that it automatically finds the connection order of singularities, hence it is easy to follow features across scales. As an example, we visualize the orbits of corner points, and compare some criterions to measure their significance.
