Detailed Description

vcurvature -- 3d curvature computations.

Description
3d curvature computations. For each surface voxel, a curvature feature is computed. Surface voxels are defined by a threshold. The algorithm is based on discrete approximations to second-order derivatives and the Weingarten equations.
