NAME

       ('mia\-2dstack\-cmeans\-presegment',)  -  Pre-classify  the  input image series by using a
       c-means estimator

SYNOPSIS

       mia-2dstack-cmeans-presegment -i <in-file> -o <out-mask> -L <label> [options]

DESCRIPTION

       mia-2dstack-cmeans-presegment This program first evaluates a sparse histogram of an  input
       image  series,  then  runs a c-means classification over the histogram, and then estimates
       the mask for one (given) class based on class probabilities.  This  program  accepts  only
       images of eight or 16 bit integer pixels.
