thresholdDoG

Applies a Difference-of-Gaussian filter to an image and thresholds it with given sigma and threshold values.

Categories: Segmentation, Binary

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_thresholdDoG(Image input, Image destination, Number sigma1, Number sigma2, Number threshold, Boolean above_threshold);

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 sigma1 = 1.0;
float sigma2 = 2.0;
float threshold = 3.0;
boolean above_threshold = true;
// Execute operation on GPU
clijx.thresholdDoG(input, destination, sigma1, sigma2, threshold, above_threshold);
// 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);
sigma1 = 1.0;
sigma2 = 2.0;
threshold = 3.0;
above_threshold = true;
% Execute operation on GPU
clijx.thresholdDoG(input, destination, sigma1, sigma2, threshold, above_threshold);
% show result
destination = clijx.pullMat(destination)

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