Usage in ImageJ macro

Ext.CLIJ2_connectedComponentsLabelingBox(Image binary_input, Image labeling_destination);

Usage in object oriented programming languages

Java
// init CLIJ and GPU
import net.haesleinhuepf.clij2.CLIJ2;
import net.haesleinhuepf.clij.clearcl.ClearCLBuffer;
CLIJ2 clij2 = CLIJ2.getInstance();

// get input parameters
ClearCLBuffer binary_input = clij2.push(binary_inputImagePlus);
labeling_destination = clij2.create(binary_input);
// Execute operation on GPU
clij2.connectedComponentsLabelingBox(binary_input, labeling_destination);
// show result
labeling_destinationImagePlus = clij2.pull(labeling_destination);
labeling_destinationImagePlus.show();

// cleanup memory on GPU
clij2.release(binary_input);
clij2.release(labeling_destination);
Matlab
% init CLIJ and GPU
clij2 = init_clatlab();

% get input parameters
binary_input = clij2.pushMat(binary_input_matrix);
labeling_destination = clij2.create(binary_input);
% Execute operation on GPU
clij2.connectedComponentsLabelingBox(binary_input, labeling_destination);
% show result
labeling_destination = clij2.pullMat(labeling_destination)

% cleanup memory on GPU
clij2.release(binary_input);
clij2.release(labeling_destination);
Icy JavaScript
// init CLIJ and GPU
importClass(net.haesleinhuepf.clicy.CLICY);
importClass(Packages.icy.main.Icy);

clij2 = CLICY.getInstance();

// get input parameters
binary_input_sequence = getSequence();
binary_input = clij2.pushSequence(binary_input_sequence);
labeling_destination = clij2.create(binary_input);
// Execute operation on GPU
clij2.connectedComponentsLabelingBox(binary_input, labeling_destination);
// show result
labeling_destination_sequence = clij2.pullSequence(labeling_destination)
Icy.addSequence(labeling_destination_sequence);
// cleanup memory on GPU
clij2.release(binary_input);
clij2.release(labeling_destination);
