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

trace - Function call trace
debug - Debug output
info - Low level messages
message - Normal messages
warning - Warnings
fail - Report test failures
error - Report 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

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

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

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
