absoluteDifference

Determines the absolute difference pixel by pixel between two images.

f(x, y) = |x - y|

Parameters

source1 : Image The input image to be subtracted from. source2 : Image The input image which is subtracted. destination : Image The output image where results are written into.

Category: Math

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_absoluteDifference(Image source1, Image source2, Image 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 source1 = clij2.push(source1ImagePlus);
ClearCLBuffer source2 = clij2.push(source2ImagePlus);
destination = clij2.create(source1);


// Execute operation on GPU
clij2.absoluteDifference(source1, source2, destination);

// show result
destinationImagePlus = clij2.pull(destination);
destinationImagePlus.show();

// cleanup memory on GPU
clij2.release(source1);
clij2.release(source2);
clij2.release(destination);
Matlab 
% init CLIJ and GPU
clij2 = init_clatlab();

% get input parameters
source1 = clij2.pushMat(source1_matrix);
source2 = clij2.pushMat(source2_matrix);
destination = clij2.create(source1);


% Execute operation on GPU
clij2.absoluteDifference(source1, source2, destination);

% show result
destination = clij2.pullMat(destination)

% cleanup memory on GPU
clij2.release(source1);
clij2.release(source2);
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
source1_sequence = getSequence();
source1 = clij2.pushSequence(source1_sequence);
source2_sequence = getSequence();
source2 = clij2.pushSequence(source2_sequence);
destination = clij2.create(source1);


// Execute operation on GPU
clij2.absoluteDifference(source1, source2, destination);

// show result
destination_sequence = clij2.pullSequence(destination)
Icy.addSequence(destination_sequence);
// cleanup memory on GPU
clij2.release(source1);
clij2.release(source2);
clij2.release(destination);
clEsperanto Python (experimental) 
import pyclesperanto_prototype as cle
