Discussion Model to image registration Optimize over SO, shape parametes Moving from App level representation towards the lower level in ITK (e.g. to share among apps such as V3D, GoFigure,...) Create a itk::GraphObject ? Use Boost graph library ? (as a module) Nick wrote one...(at the time we didn't want Boost..) Data in nodes & data in edges (e.g. transforms)..

Discussion What information to put in Nodes ? What to put in Edges ? How to manage IO ? get it from boost ? Use graphviz ? ItkGraphObject Nodes Template argument Edge
