SPHARM-MAT is implemented based on a powerful 3D Fourier surface representation method called SPHARM, which creates parametric surface models using spherical harmonics. It is a matlab-based 3D shape modeling and analysis toolkit, and is designed to aid statistical shape analysis for relating morphometric changes in 3D structures of interest to different conditions. The project is supported by NIBIB R03EB008674.

SPHARM-MAT v1.0.0 is released: Download, Documentation (PDF), NITRC
