Module Description

This module is a tool to generate closed contours on a surface in 3D. The contour is initialized with a set of points, and subsequently 'evolves' according to some geometric criterion of the underlying surface (e.g. Surface Normal, mean curvature, second fundamental form, etc) and the embedded curve (e.g. geodesic & normal curvatures, etc ).

The implementation uses a version of Sparse Field Level Sets (Whitaker et al 1998) modified for a mesh where there is an arbitrary number of vertex neighbors.

While the motivating problem is segmentation of Sulci & Gyri on the cortical surface, the technique is also applicable to analysis of other anatomic structures (e.g. bones and fractures thereof).
