[Insight-developers] Active shape models

[Martin Styner]

Hi Tobias
Just for clarification, the patent that Luis was talking about is in  
regard to Active Shape Models and does not overlap with your  
automatic correspondence algorithm. Also, the Manchester group has  
been very open in regard to the ASM patent and academia. But one has  
to consult them before using ASM in any commercial product.
Btw, the method that was mentioned by Luis is for a set of  
distinctive landmarks and is optimal for unstructured pointset (small  
number of disconnected landmarks), whereas  the method Tobias is  
referring to is great for surface meshes of spherical topology. I  
myself will be submitting classes for an automatic correspondence  
method (SPHARM correspondence for surface meshes, see also
http://www.na-mic.org/Wiki/index.php/Progress_Report:Shape_Analysis )  
to the Insight Journal and will use the same base-classes as Tobias  
does.
Best regards
Martin
