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 ... 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)
