PROGRAM:

NAME


mia-2dimagestack-cmeans - Calculate the c-means classification for a series of images.

SYNOPSIS


mia-2dimagestack-cmeans -i <in-file> -o <out-probmap> [options]

DESCRIPTION


mia-2dimagestack-cmeans This program first evaluates a sparse histogram of an input image
series, then runs a c-means classification over the histogram and then writes the
probability mapping for thr original intensity values

OPTIONS


File-IO
-i --in-file=(input, required); io
input image(s) to be filtered For supported file types see
PLUGINS:2dimage/io

-o --out-probmap=(output, required); string
Save probability map to this file

Help & Info
-V --verbose=warning
verbosity of output, print messages of given level and higher priorities.
Supported priorities starting at lowest level are:
info ‐ Low level messages
trace ‐ Function call trace
fail ‐ Report test failures
warning ‐ Warnings
error ‐ Report errors
debug ‐ Debug output
message ‐ Normal messages
fatal ‐ Report only fatal errors

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.

EXAMPLE


Run the program over images imageXXXX.png with the sparse histogram, threshold the lower
5% bins (if available), run cmeans with three classes on the non-zero pixels.

mia-2dimagestack-cmeans -i image0000.png -o cmeans,txt --histogram-tresh=5 --classes 3
