Abstract

Modern medical imaging techniques, such as Magnetic Resonance Imaging (MRI) or X-ray computed tomography provide three dimensional images of internal structures of the body, usually by means of a stack of tomographic images. The first stage in the automatic analysis of such data is 3D edge detection [1,2] which provides points corresponding to the boundaries of the surfaces forming the 3D structure. The next stage is to characterize the local geometry of these surfaces in order to extract points or lines on which registration and/or tracking procedures can rely [3,4,5,6].
