minimumBox

Computes the local minimum of a pixels rectangular neighborhood.

The rectangles size is specified by its half-width and half-height (radius).

Usage in ImageJ macro

Ext.CLIJ2_minimumBox(Image source, Image destination, Number radiusX, Number radiusY);

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);
destination = clij2.create(source);
int radiusX = 10;
int radiusY = 20;

// Execute operation on GPU
clij2.minimumBox(source, destination, radiusX, radiusY);

// show result
destinationImagePlus = clij2.pull(destination);
destinationImagePlus.show();

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

Matlab

% init CLIJ and GPU
clij2 = init_clatlab();
% get input parameters
source = clij2.pushMat(source_matrix);
destination = clij2.create(source);
radiusX = 10;
radiusY = 20;

% Execute operation on GPU
clij2.minimumBox(source, destination, radiusX, radiusY);

% show result
destination = clij2.pullMat(destination)

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

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);
destination = clij2.create(source);
radiusX = 10;
radiusY = 20;

// Execute operation on GPU
clij2.minimumBox(source, destination, radiusX, radiusY);

// show result
destination_sequence = clij2.pullSequence(destination)
Icy.addSequence(destination_sequence);
// cleanup memory on GPU
clij2.release(source);
clij2.release(destination);

clEsperanto Python (experimental)
