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=(input, required); 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

trace ‐ Function call trace
fail ‐ Report test failures
warning ‐ Warnings
error ‐ Report errors
debug ‐ Debug output
message ‐ Normal messages
fatal ‐ Report only fatal errors

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).

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')

Supported element types:

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:

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

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
