Objective

We are porting to ITK the spherical mesh registration method described in the paper [1]. A framework for supporting Spherical Mesh Registration is being designed and implemented.

Approach, Plan

The Spherical Diffeomorphic Demons method is described in detail in the paper [1].

Our plan for the project includes

1. Implement readers for the surface file format of FreeSurfer
2. Implement a software framework for Mesh Registration
3. Use the QuadEdgeMesh for representing spherical meshes.
4. Implement rigid Mesh registration
5. Implement a smoothing filter for scalar data in a Mesh.
6. Implement the DiffeomorphicDemons filter for QuadEdgeMeshes.

Progress

• The framework for Rigid registration of Spherical Meshes has been implemented. The source code is available in the NAMIC Sandbox directory QuadEdgeMeshRigidRegistration.
• The code for the Diffeomorphic Demons method is under development. The current version of the source code can be found in the NAMIC Sandbox directory QuadEdgeMeshSphericalDiffeomorphicDemonsRegistration
