sumOfAllPixels

Determines the sum of all pixels in a given image.

It will be stored in a new row of ImageJs Results table in the column ‘Sum’.

Parameters

source : Image The image of which all pixels or voxels will be summed.

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_sumOfAllPixels(Image source);

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 source = clij2.push(sourceImagePlus);

// Execute operation on GPU
double resultSumOfAllPixels = clij2.sumOfAllPixels(source);

// show result
System.out.println(resultSumOfAllPixels);

// cleanup memory on GPU
clij2.release(source);

Matlab

% init CLIJ and GPU
clij2 = init_clatlab();

% get input parameters
source = clij2.pushMat(source_matrix);

% Execute operation on GPU
double resultSumOfAllPixels = clij2.sumOfAllPixels(source);

% show result
System.out.println(resultSumOfAllPixels);

% cleanup memory on GPU
clij2.release(source);

Icy JavaScript

// init CLIJ and GPU
importClass(net.haesleinhuepf.clicy.CLICY);
importClass(Packages.icy.main.Icy);

clij2 = CLICY.getInstance();

// get input parameters
source_sequence = getSequence();
source = clij2.pushSequence(source_sequence);

// Execute operation on GPU
double resultSumOfAllPixels = clij2.sumOfAllPixels(source);

// show result
System.out.println(resultSumOfAllPixels);

// cleanup memory on GPU
clij2.release(source);
