standardDeviationOfMaskedPixels

Determines the standard deviation of all pixels in an image which have non-zero value in a corresponding mask image.

The value will be stored in a new row of ImageJs Results table in the column ‘Masked_standard_deviation’.

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_standardDeviationOfMaskedPixels(Image source, Image mask);

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);
ClearCLBuffer mask = clij2.push(maskImagePlus);

// Execute operation on GPU
double resultStandardDeviationOfMaskedPixels = clij2.standardDeviationOfMaskedPixels(source, mask);

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

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

Matlab

% init CLIJ and GPU
clij2 = init_clatlab();

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

% Execute operation on GPU
double resultStandardDeviationOfMaskedPixels = clij2.standardDeviationOfMaskedPixels(source, mask);

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

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

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);
mask_sequence = getSequence();
mask = clij2.pushSequence(mask_sequence);

// Execute operation on GPU
double resultStandardDeviationOfMaskedPixels = clij2.standardDeviationOfMaskedPixels(source, mask);

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

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