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=(input, required); 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
Help & Info
-V --verbose=warning
verbosity of output, print messages of given level and higher priorities.
Supported priorities starting at lowest level are:
info ‐ Low level messages
trace ‐ Function call trace
fail ‐ Report test failures
warning ‐ Warnings
error ‐ Report errors
debug ‐ Debug output
message ‐ Normal messages
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).
