NAME
mia-2dstack-cmeans-presegment - Pre-classify the input image series by using a c-means estimator
SYNOPSIS
mia-2dstack-cmeans-presegment -i <in-file> -o <out-mask> -L <label> [options]
DESCRIPTION
mia-2dstack-cmeans-presegment This program first evaluates a sparse histogram of an input image series, then runs a c-means classification over the histogram, and then estimates the mask for one (given) class based on class probabilities. This program accepts only images of eight or 16 bit integer pixels.
OPTIONS
File-IO -i --in-file=(input, required); io input image(s) to be filtered For supported file types see PLUGINS:2dimage/io -p --out-probmap=(output); string Save probability map to this file -t --type=png output file name type -o --out-mask=(required, output); string output file name base 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 --copyright print copyright information -h --help print this help -? --usage print a short help --version print the version number and exit Parameters -T --histogram-thresh=5; float in [0, 50] Percent of the extrem parts of the histogram to be collapsed into the respective last histogram bin. -C --classes=kmeans:nc=3 C-means class initializer For supported plugins see PLUGINS:1d/cmeans -S --seed-threshold=0.95; float in (0, 1) Probability threshold value to consider a pixel as seed pixel. -L --label=(required); int in [0, 10] Class label to create the mask from 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: 1d/cmeans
even C-Means initializer that sets the initial class centers as evenly distributed over [0,1], supported parameters are: nc =(required, ulong) Number of classes to use for the fuzzy-cmeans classification. kmeans C-Means initializer that sets the initial class centers by using a k-means classification, supported parameters are: nc =(required, ulong) Number of classes to use for the fuzzy-cmeans classification. predefined C-Means initializer that sets pre-defined values for the initial class centers, supported parameters are: cc =(required, vdouble) Initial class centers fuzzy-cmeans classification (normalized to range [0,1]).

EXAMPLE
Run the program over images imageXXXX.png with the sparse histogram, threshold the lower 30% bins (if available), run cmeans with two classes on the non-zero pixels and then create the mask for class 1 as foregroundXXXX.png. mia-2dstack-cmeans-presegment -i imageXXXX.png -o foreground -t png --histogram-tresh=30 --classes 2 --label 1
