reduceLabelsToLabelEdges

Takes a label map and reduces all labels to their edges. Label IDs stay the same and background will be zero.

Category: 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_reduceLabelsToLabelEdges(Image input_labels, Image destination_labels);

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 input_labels = clijx.push(input_labelsImagePlus);
destination_labels = clijx.create(input_labels);

// Execute operation on GPU
clijx.reduceLabelsToLabelEdges(input_labels, destination_labels);

// show result
destination_labelsImagePlus = clijx.pull(destination_labels);
destination_labelsImagePlus.show();

// cleanup memory on GPU
clijx.release(input_labels);
clijx.release(destination_labels);

Matlab

% init CLIJ and GPU
clijx = init_clatlabx();

% get input parameters
input_labels = clijx.pushMat(input_labels_matrix);
destination_labels = clijx.create(input_labels);

% Execute operation on GPU
clijx.reduceLabelsToLabelEdges(input_labels, destination_labels);

% show result
destination_labels = clijx.pullMat(destination_labels)

% cleanup memory on GPU
clijx.release(input_labels);
clijx.release(destination_labels);
