generateBinaryOverlapMatrix

Takes two labelmaps with n and m labels and generates a (n+1)*(m+1) matrix where all pixels are set to 0 exept those where labels overlap between the label maps.

For example, if labels 3 in labelmap1 and 4 in labelmap2 are touching then the pixel (3,4) in the matrix will be set to 1.

ClearCLBuffer label_map2 = clij2.push(label_map2ImagePlus);
binary_overlap_matrix_destination = clij2.create(label_map1);

// Execute operation on GPU
clij2.generateBinaryOverlapMatrix(label_map1, label_map2, binary_overlap_matrix_destination);

// show result
binary_overlap_matrix_destinationImagePlus = clij2.pull(binary_overlap_matrix_destination);
binary_overlap_matrix_destinationImagePlus.show();

// cleanup memory on GPU
clij2.release(label_map1);
clij2.release(label_map2);
clij2.release(binary_overlap_matrix_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);
binary_overlap_matrix_destination = clij2.create(label_map1);

% Execute operation on GPU
clij2.generateBinaryOverlapMatrix(label_map1, label_map2, binary_overlap_matrix_destination);

% show result
binary_overlap_matrix_destination = clij2.pullMat(binary_overlap_matrix_destination)

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

Icy JavaScript

// init CLIJ and GPU
importClass(net.haesleinhuepf.clicy.CLICY);
