# mia-2dfuzzysegment(1)

A fuzzy c-means segmentation of a 2D image

## NAME

mia-2dfuzzysegment - A fuzzy c-means segmentation of a 2D image

## SYNOPSIS

**mia-2dfuzzysegment -i \<in-file\> \[options\]**

## DESCRIPTION

**mia-2dfuzzysegment** This program runs a combined fuzzy c-means clustering and B-field correction to facilitate a fuzzy segmentation of 2D image. cf D.L. Pham and J.L.Prince, "An adaptive fuzzy C-means algorithm for image segmentation in the presence of intensity inhomogeneities", Pat. Rec. Let., 20:57-68,1999

## OPTIONS

### File-IO

- \-i --in-file=(required, input); io

  input image(s) to be segmenetd\
    For supported file types see PLUGINS:2dimage/io

- \-c --cls-file=(output); io

  output class probability images (floating point values and multi-image)\
    For supported file types see PLUGINS:2dimage/io

- \-o --b0-file=(output); io

  image corrected for intensity non-uniformity\
    For supported file types see PLUGINS:2dimage/io

- \-g --gain-file=(output); io

  gain field (floating point valued)\
    For supported file types see PLUGINS:2dimage/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

- \-r --residuum=0.1

  relative residuum

- \--l1=200000

  Penalize magnitude of intensity inhomogeinity correction

- \--l2=2e+06

  Smoothness of intensity inhomogeinity correction

### 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).

## EXAMPLE

Run a 5-class segmentation over input image input.v and store the class probability images in cls.v and the B0-field corrected image in b0.v.

mia-2dfuzzysegment -i input.v -c 5 -o b0.v -c cls.v
