The UNC shape analysis framework is an automatic shape correspondence methodology that uses spherical harmonics for sampling (SPHARM-PDM). ShapeAnalysisModule computes point-based models using a parametric boundary description. The point-based models computed with this tool are used to perform statistical studies (within shapeAnalysisMANCOVA) or to get correspondence point Models(within ParticleModule). The ParticleModule is already part of the ShapeAnalysisModule. You can choose to run it or not. Nevertheless, some triangulation of spherical harmonics are not preserved, not surprisingly.

Objective

The goal is to improve the Particle Module. We need to set template population that not change their correspondence. That is to say, we have to know how to fix a template for the Particle study.

Approach, Plan

Our plan for the project week is to:

• Meet with all interested parties
• Decided how we are going to fix the template

Progress

A template has been set. We are still testing the improvement of this add on our results.
