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

mia-2dsegment-local-kmeans -i <in-file> [options]

mia-2dsegment-local-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.

image to be segmented
For supported file types see PLUGINS:2dimage/io
class label image based on merging local labels
For supported file types see PLUGINS:2dimage/io
class label image based on classifying by using the interpolated class centers
For supported file types see PLUGINS:2dimage/io
Save the class center images to a debug file (type is double)
For supported file types see PLUGINS:2dimage/io

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.

Run the segmentation on image test.png using three classes, local regions of 40 pixels (grid width 20 pixels), and a class ignore threshold of 0.01.

mia-2dsegment-local-kmeans -i test.png -o label.png -n 3 -g 20 -t 0.01
