labelOverlapCountMap

By Robert Haase, Kisha Sivanathan

Takes two label maps, and counts for every label in label map 1 how many labels overlap with it in label map 2.

The resulting map is generated from the label map 1 by replacing the labels with the respective count.

Availability: Available in Fiji by activating the update sites clij and clij2. This function is part of clij2_-2.5.0.1.jar.

Usage in ImageJ macro

Ext.CLIJ2_labelOverlapCountMap(Image label_map1, Image label_map2, Image overlap_count_map_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 label_map1 = clij2.push(label_map1ImagePlus);
ClearCLBuffer label_map2 = clij2.push(label_map2ImagePlus);
overlap_count_map_destination = clij2.create(label_map1);

// Execute operation on GPU
clij2.labelOverlapCountMap(label_map1, label_map2, overlap_count_map_destination);

// show result
overlap_count_map_destinationImagePlus = clij2.pull(overlap_count_map_destination);
overlap_count_map_destinationImagePlus.show();

// cleanup memory on GPU
clij2.release(label_map1);
clij2.release(label_map2);
clij2.release(overlap_count_map_destination);

Matlab

% init CLIJ and GPU
clij2 = init_clatlab();

% get input parameters
label_map1 = clij2.pushMat(label_map1_matrix);
label_map2 = clij2.pushMat(label_map2_matrix);
overlap_count_map_destination = clij2.create(label_map1);

% Execute operation on GPU
clij2.labelOverlapCountMap(label_map1, label_map2, overlap_count_map_destination);

% show result
overlap_count_map_destination = clij2.pullMat(overlap_count_map_destination)

% cleanup memory on GPU
clij2.release(label_map1);
clij2.release(label_map2);
clij2.release(overlap_count_map_destination);

Icy JavaScript

// init CLIJ and GPU
importClass(net.haesleinhuepf.clicy.CLICY);
importClass(Packages.icy.main.Icy);

clij2 = CLICY.getInstance();

// get input parameters
label_map1_sequence = getSequence();
label_map1 = clij2.pushSequence(label_map1_sequence);
label_map2_sequence = getSequence();
label_map2 = clij2.pushSequence(label_map2_sequence);
overlap_count_map_destination = clij2.create(label_map1);

// Execute operation on GPU
clij2.labelOverlapCountMap(label_map1, label_map2, overlap_count_map_destination);

// show result
overlap_count_map_destination_sequence = clij2.pullSequence(overlap_count_map_destination)
Icy.addSequence(overlap_count_map_destination_sequence);
// cleanup memory on GPU
clij2.release(label_map1);
clij2.release(label_map2);
clij2.release(overlap_count_map_destination);
