# NAME¶

SurfaceCurvature - part of ANTS registration suite

# DESCRIPTION¶

- This implements The Shape Operator for Differential Analysis of Images
(google for the pdf) By B. Avants and J.C. Gee Documentation is on demand
**---**if there is enough interest, documentation will improve. There are several modes of operation and you must try parameters and input either binary or gray scale images to see the different effects**----**experimentation or reading the (minimal) documentation / paper / code is needed to understand the program usage : SurfaceCurvature FileNameIn FileNameOut sigma option e.g : SurfaceCurvature BrainIn.nii BrainOut.nii 3 0 option 0 means just compute mean curvature from intensity option 5 means characterize surface from intensity option 6 means compute gaussian curvature option 7 means surface area ... for surface characterization 1 == (+) bowl 2 == (-) bowl 3 == (+) saddle 4 == (-) saddle 5 == (+) U 6 == (-) U 7 == flat 8 == a perfectly even saddle (rare) - we add 128 to mean curvature results s.t. they are differentiated from background (zero)
