('mia\-2dsegment\-per\-pixel\-kmeans',) - Run a k-means segmentation of a 2D image.

mia-2dsegment-per-pixel-kmeans -i <in-file> -o <out-file> [options]

mia-2dsegment-per-pixel-kmeans This program runs the segmentation of a 2D image by applying a localized k-means approach that helps to overcome intensity inhomogeneities in the image. The approach evaluates a global k-means clustering, and then separates the image into overlapping regions where more k-means iterations are run only including the locally present classes, i.e. the classes that relatively contain more pixels than a given threshold.

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

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).

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.
