euclideanDistanceFromLabelCentroidMap

Takes a label map, determines the centroids of all labels and writes the distance of all labelled pixels to their centroid in the result image. Background pixels stay zero.

Categories: Measurements, Labels

Availability: Available in Fiji by activating the update sites clij and clij2. This function is part of clijx_-0.30.1.21.jar.

Usage in ImageJ macro

Ext.CLIJx_euclideanDistanceFromLabelCentroidMap(Image labelmap_input, Image destination);

Usage in object oriented programming languages

Java

// init CLIJ and GPU
import net.haesleinhuepf.clijx.CLIJx;
import net.haesleinhuepf.clij.clearcl.ClearCLBuffer;
CLIJx clijx = CLIJx.getInstance();

// get input parameters
ClearCLBuffer labelmap_input = clijx.push(labelmap_inputImagePlus);
destination = clijx.create(labelmap_input);

// Execute operation on GPU
clijx.euclideanDistanceFromLabelCentroidMap(labelmap_input, destination);

// show result
destinationImagePlus = clijx.pull(destination);
destinationImagePlus.show();

// cleanup memory on GPU
clijx.release(labelmap_input);
clijx.release(destination);

Matlab

% init CLIJ and GPU
clijx = init_clatlabx();

% get input parameters
labelmap_input = clijx.pushMat(labelmap_input_matrix);
destination = clijx.create(labelmap_input);

% Execute operation on GPU
clijx.euclideanDistanceFromLabelCentroidMap(labelmap_input, destination);

% show result
destination = clijx.pullMat(destination)

% cleanup memory on GPU
clijx.release(labelmap_input);
clijx.release(destination);
