sorensenDiceCoefficient

Determines the overlap of two binary images using the Sorensen-Dice coefficent.

A value of 0 suggests no overlap, 1 means perfect overlap. The Sorensen-Dice coefficient is saved in the colum ‘Sorensen_Dice_coefficient’. Note that the Sorensen-Dice coefficient s can be calculated from the Jaccard index j using this formula:

s = f(j) = 2 j / (j + 1)

Usage in ImageJ macro

Ext.CLIJ2_sorensenDiceCoefficient(Image source1, Image source2);

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 source1 = clij2.push(source1ImagePlus);
ClearCLBuffer source2 = clij2.push(source2ImagePlus);

// Execute operation on GPU
double resultSorensenDiceCoefficient = clij2.sorensenDiceCoefficient(source1, source2);

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

// cleanup memory on GPU
clij2.release(source1);
clij2.release(source2);

Matlab

% init CLIJ and GPU
clij2 = init_clatlab();

% get input parameters
source1 = clij2.pushMat(source1_matrix);
source2 = clij2.pushMat(source2_matrix);

% Execute operation on GPU
double resultSorensenDiceCoefficient = clij2.sorensenDiceCoefficient(source1, source2);

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

% cleanup memory on GPU
clij2.release(source1);
clij2.release(source2);

Icy JavaScript

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

clij2 = CLICY.getInstance();

// get input parameters
source1_sequence = getSequence();
source1 = clij2.pushSequence(source1_sequence);
source2_sequence = getSequence();
source2 = clij2.pushSequence(source2_sequence);

// Execute operation on GPU
double resultSorensenDiceCoefficient = clij2.sorensenDiceCoefficient(source1, source2);

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

// cleanup memory on GPU
clij2.release(source1);
clij2.release(source2);
