vcurvature -- 3d curvature computations Description.RS 4 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. Reference:.RS 4 O. Monga, S. Benayoun (1995). 'Using partial derivatives of 3D images to extract typical surface features', Computer Vision and Image Understanding, Vol.61, No.2, pp.171--189. Usage.RS 4 vcurvature Parameters: -in input image -out output image -t iso-value. Default: 0.5 -ctype type of output (class | mean | gauss). Default: class -border Whether to process only border voxels (true | false) Examples.RS 4 Known bugs.RS 4 none. Author: G.Lohmann, MPI-CBS, 2004
