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

-p --out-probmap=(output); string
Save probability map to this file
-t --type=png
output file name type
-o --out-mask=(output, required); string

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
