replaceIntensities

Replaces integer intensities specified in a vector image.

The vector image must be 3D with size (m, 1, 1) where m corresponds to the maximum intensity in the original image. Assuming the vector image contains values (0, 1, 0, 2) means:

Usage in ImageJ macro

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 input = clij2.push(inputImagePlus);
ClearCLBuffer new_values_vector = clij2.push(new_values_vectorImagePlus);
destination = clij2.create(input);
// Execute operation on GPU
clij2.replaceIntensities(input, new_values_vector, destination);
// show result
destinationImagePlus = clij2.pull(destination);
destinationImagePlus.show();

// cleanup memory on GPU
clij2.release(input);
clij2.release(new_values_vector);
clij2.release(destination);
Matlab
% init CLIJ and GPU
clij2 = init_clatlab();

% get input parameters
input = clij2.pushMat(input_matrix);
new_values_vector = clij2.pushMat(new_values_vector_matrix);
destination = clij2.create(input);
% Execute operation on GPU
clij2.replaceIntensities(input, new_values_vector, destination);
% show result
destination = clij2.pullMat(destination)

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

clij2 = CLICY.getInstance();

// get input parameters
input_sequence = getSequence();
input = clij2.pushSequence(input_sequence);
new_values_vector_sequence = getSequence();
new_values_vector = clij2.pushSequence(new_values_vector_sequence);
destination = clij2.create(input);
// Execute operation on GPU
clij2.replaceIntensities(input, new_values_vector, destination);
// show result
destination_sequence = clij2.pullSequence(destination)
Icy.addSequence(destination_sequence);
// cleanup memory on GPU
clij2.release(input);
clij2.release(new_values_vector);
clij2.release(destination);
