replaceIntensity

Replaces a specific intensity in an image with a given new value.

Category: Filter

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

replaceIntensity often follows after

subtractImages (1)
multiplyImages (1)

replaceIntensity is often followed by

equal (1)

Usage in ImageJ macro

Ext.CLIJ2_replaceIntensity(Image input, Image destination, Number value_to_replace, Number value_replacement);

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);
destination = clij2.create(input);
float value_to_replace = 1.0;
float value_replacement = 2.0;

// Execute operation on GPU
clij2.replaceIntensity(input, destination, value_to_replace, value_replacement);

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

// cleanup memory on GPU
clij2.release(input);
clij2.release(destination);

Matlab

% init CLIJ and GPU
clij2 = init_clatlab();

% get input parameters
input = clij2.pushMat(input_matrix);
destination = clij2.create(input);
value_to_replace = 1.0;
value_replacement = 2.0;

% Execute operation on GPU
clij2.replaceIntensity(input, destination, value_to_replace, value_replacement);

% show result
destination = clij2.pullMat(destination)

% cleanup memory on GPU
clij2.release(input);
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);
destination = clij2.create(input);
value_to_replace = 1.0;
value_replacement = 2.0;

// Execute operation on GPU
clij2.replaceIntensity(input, destination, value_to_replace, value_replacement);

// show result
destination_sequence = clij2.pullSequence(destination)
Icy.addSequence(destination_sequence);
// cleanup memory on GPU
clij2.release(input);
clij2.release(destination);

clEsperanto Python (experimental)

import pyclesperanto_prototype as cle

cle.replace_intensity(input, destination, value_to_replace, value_replacement)
