NAME

       mia-3dsegment-ahmed - Run a fuzzy c-means segmentation of a 3D image.

SYNOPSIS

       mia-3dsegment-ahmed -i <in-file> -c <class-file> [options]

DESCRIPTION

       mia-3dsegment-ahmed  This program implements a variation of the paper:Mohamed N. Ahmed et.
       al, "A Modified Fuzzy C-Means Algorithm for Bias Field estimation and Segmentation of  MRI
       Data",  IEEE  Trans. on Medical Imaging, Vol. 21, No. 3, March 2002, changes are: p=2, and
       exp

OPTIONS

   File-IO
              -i --in-file=(required, input); io
                     image to be segmented
                      For supported file types see PLUGINS:3dimage/io

              -c --class-file=(output, required); io
                     class probability images, the image type must support  multiple  images  and
                     floating point values
                      For supported file types see PLUGINS:3dimage/io

              -b --out-file=(output); io
                     Bias  corrected image will be of the same type like the input image. If this
                     parameter is not given, then the bias correction will not be applied.
                      For supported file types see PLUGINS:3dimage/io

   Processing
                 --threads=-1
                     Maxiumum number of threads to use for processing,This number should be lower
                     or equal to the number of logical  processor  cores  in  the  machine.  (-1:
                     automatic estimation).
