<p>Update from Wiki</p> <p><b>New page</b></p><div>== Shape Correspondence Based on Local Curvature ==<br /> <br /> === Description ===<br /> <br /> We are working on a correspondence method based on local curvature. This is a population based method (a la MDL or DetCov) that optimizes correspondence for a population, rather than pair-based. Currently we use the Koenderink measure C and S as our correspondence metric. However, the code is structured in such a way to enable very easy modification of the metric.<br /> <br /> === Current Status &amp; Plans for Project Week ===<br /> <br /> There still is plenty of room for improvements, but the code is working right now. We have tried it in a very small dataset for debugging, and the optimization seems to properly converge.<br /> <br /> We also tried on the caudate dataset, and it seemed to work properly, although we dont yet have a visualization method in place. This is one of the things we want to accomplish at Project Week: coming up with a nice visualization of the correspondence results with the KWMeshVisu tool that we developed at the previous programming week.<br /> <br /> We are also in contact with Tobias Heimann who is the original author of a large part of the ITK classes we are using, and we plan to make a combined submission with him to MICCAI open source workshop. The paper is also one of the major things that we want to work on during the week.<br /> <br /> === Members ===<br /> <br /> * Ipek Oguz (UNC)<br /> * Martin Styner (UNC)</div>
