mia-2dsegment-ahmed1

Run a fuzzy c-means segmentation of a 2d image.

Usage

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

Overview

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, ⟨https://doi.org/10.1109/42.996338⟩

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=(required, output); 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 classes

-b --bias-correct

apply bias field correction

-c --class-centres=

initial class centers

-s --spread=64

spread parameter describing the strength of mattar distinction

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

-h --help

print this help

-? --usage

print a short help

--version

print the version number and exit

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).

PLUGINS: 2dimage/io

bmp

BMP 2D-image input/output support. The plug-in supports reading and writing of binary images and 8-bit gray scale images. read-only support is provided for 4-bit gray scale images. The color table is ignored and the pixel values are taken as literal gray scale values.

Recognized file extensions: .BMP, .bmp

Supported element types:

binary data, unsigned 8 bit

datapool

Virtual IO to and from the internal data pool

Recognized file extensions: .@

dicom

2D image io for DICOM

Recognized file extensions: .DCM, .dcm

jpg

a 2dimage io plugin for jpeg gray scale images

Recognized file extensions: .JPEG, .JPG, .jpeg, .jpg

Supported element types:

unsigned 8 bit

png

a 2dimage io plugin for png images

Recognized file extensions: .PNG, .png

Supported element types:

binary data, unsigned 8 bit, unsigned 16 bit

raw

RAW 2D-image output support

Recognized file extensions: .RAW, .raw

Supported element types:

binary data, signed 8 bit, unsigned 8 bit, signed 16 bit, unsigned 16 bit, signed 32 bit, unsigned 32 bit, floating point 32 bit, floating point 64 bit

tif

TIFF 2D-image input/output support

Recognized file extensions: .TIF, .TIFF, .tif, .tiff

Supported element types:

binary data, unsigned 8 bit, unsigned 16 bit, unsigned 32 bit

vista

a 2dimage io plugin for vista images

Recognized file extensions: .-, .V, .VISTA, .v, .vista

Supported element types:

binary data, signed 8 bit, unsigned 8 bit, signed 16 bit, unsigned 16 bit, signed 32 bit, unsigned 32 bit, floating point 32 bit, floating point 64 bit

Examples

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

mia-2dsegment-ahmed -i input.v -a 5 -o cls.v
