divideScalarByImage

Divides a scalar s by image X pixel wise.

f(s, x) = s / x

Category: Math

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_divideScalarByImage(Image image, Image destination, Number scalar);

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 image = clijx.push(imageImagePlus);
destination = clijx.create(image);
float scalar = 1.0;

// Execute operation on GPU
clijx.divideScalarByImage(image, destination, scalar);

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

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

Matlab

% init CLIJ and GPU
clijx = init_clatlabx();

% get input parameters
image = clijx.pushMat(image_matrix);
destination = clijx.create(image);
scalar = 1.0;

% Execute operation on GPU
clijx.divideScalarByImage(image, destination, scalar);

% show result
destination = clijx.pullMat(destination)

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