# mia-cmeans(1)

C-means classification of a histogram.

## NAME

mia-cmeans - C-means classification of a histogram.

## SYNOPSIS

**mia-cmeans -i \<in-file\> -o \<out-file\> \[options\]**

## DESCRIPTION

**mia-cmeans** This Program reads a histogram from stdin and evaluates a cmeans classification of the intensity values into the given number of classes.

## OPTIONS

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

  input file name containing the histogram

- \-o --out-file=(required, output); string

  output file name to store probabilities

- \-n --nclasses=3

  number of classes to partition into

- \-m --max-iter=100

  maximum number of iterations

- \-e --even-start

  start with centers evenly distributed over the histogram

- \-c --class-centers=

  initial class centers

- \-a --auto

  atomatic adaption of variance (experimental)

- \-t --cut-histo

  cut empty histogram at the end

- \-k --variance=1

  variance parameter

- \--self-test

  run self test

### 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
