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)
