NAME

mia-2dsegment-ahmed - Run a fuzzy c-means segmentation of a 2D image.

SYNOPSIS

mia-2dsegment-ahmed -i <in-file> -o <out-file> [options]

DESCRIPTION

mia-2dsegment-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

-i --in-file=(input, required); io
image to be segmented For supported file types see PLUGINS:2dimage/io

-o --out-file=(output, required); io
class probability images, the image type must support multiple images and
floating point values For supported file types see PLUGINS:2dimage/io

-a --no-of-classes=3
number of classesnumber of classes

-b --bias-correct
apply bias field correction

-c --class-centres=
initial class centers

-s --spread=64
spread parameter describing the strength of mattar distinctionspread
parameter describing the strength of mattar distinction
