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 Segmen‐
tation 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=(required, output); 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
Help & Info
-V --verbose=warning
verbosity of output, print messages of given level and higher priorities. Supported
priorities starting at lowest level are:
trace ‐ Function call trace
debug ‐ Debug output
info ‐ Low level messages
message ‐ Normal messages
warning ‐ Warnings
fail ‐ Report test failures
error ‐ Report errors
fatal ‐ Report only fatal errors
--copyright
print copyright information
-h --help
print this help
-? --usage
print a short help
--version
print the version number and exit
Parameters
-n --no-of-classes=3
number of classes
-C --class-centres=
initial class centers, this parameter overrides 'no-of-clases'.
-s --spread=64
spread parameter describing the strength of mattar distinction
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).
