extendedDepthOfFocusTenengradProjection

Extended depth of focus projection maximizing intensity in the local sobel image.

The sigma parameter allows controlling an Gaussian blur which should smooth the altitude map.

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_extendedDepthOfFocusTenengradProjection(Image source, Image destination, Number sigma);

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 source = clijx.push(sourceImagePlus);
destination = clijx.create(source);
float sigma = 1.0;

// Execute operation on GPU
clijx.extendedDepthOfFocusTenengradProjection(source, destination, sigma);

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

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

Matlab

% init CLIJ and GPU
clijx = init_clatlabx();

% get input parameters
source = clijx.pushMat(source_matrix);
destination = clijx.create(source);
sigma = 1.0;

% Execute operation on GPU
clijx.extendedDepthOfFocusTenengradProjection(source, destination, sigma);

% show result
destination = clijx.pullMat(destination)

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