intensityCorrection

Determines the mean intensity of the image stack and multiplies it with a factor so that the mean intensity becomes equal to a given value.

Category: Filter

Availability: Available in Fiji by activating the update sites clij and clij2. This function is part of clijx_-0.32.0.1.jar.

Usage in ImageJ macro

Ext.CLIJx_intensityCorrection(Image input, Image destination, Number reference_mean_intensity);

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 = clijx.push(inputImagePlus);
destination = clijx.create(input);
float reference_mean_intensity = 1.0;

// Execute operation on GPU
clijx.intensityCorrection(input, destination, reference_mean_intensity);

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

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

Matlab

% init CLIJ and GPU
clijx = init_clatlabx();

% get input parameters
input = clijx.pushMat(input_matrix);
destination = clijx.create(input);
reference_mean_intensity = 1.0;

% Execute operation on GPU
clijx.intensityCorrection(input, destination, reference_mean_intensity);

% show result
destination = clijx.pullMat(destination)

% cleanup memory on GPU
clijx.release(input);
clijx.release(destination);
