[Insight-users] FEM Deformable Registration Details

[cbilen01 at students.poly.edu]

Hi,I make use of the FEM based deformable registration in ITK in a task as simple as in the DeformableRegistration1.cxx in ITK Examples. The algorithm works fine however I need detailed information on the algorithm, is there an academic paper or reference in which this algorithm is described? What is the energy function it minimizes for instance? I looked a lot into the manual / tutorials but found no information on that. The book on ITK has details about some concepts, but it is unclear which of the algorithms it describes is this one. I would really appreciate some help, thanks.Cagdas Bilen
