downsampleSliceBySliceHalfMedian

Scales an image using scaling factors 0.5 for X and Y dimensions. The Z dimension stays untouched.

Thus, each slice is processed separately. The median method is applied. Thus, each pixel value in the destination image equals to the median of four corresponding pixels in the source image.

Usage in ImageJ macro

Ext.CLIJ2_downsampleSliceBySliceHalfMedian(Image source, Image destination);

Usage in Java

clij2.downsampleSliceBySliceHalfMedian(source, destination);
// 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);
// Execute operation on GPU
clij2.downsampleSliceBySliceHalfMedian(source, destination);
//show result
destinationImagePlus = clij2.pull(destination);
destinationImagePlus.show();

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

Usage in Matlab

clij2.downsampleSliceBySliceHalfMedian(source, destination);
% init CLIJ and GPU
clij2 = init_clatlab();

% get input parameters
source = clij2.pushMat(source_matrix);
destination = clij2.create(source);
% Execute operation on GPU
clij2.downsampleSliceBySliceHalfMedian(source, destination);
% show result
destination = clij2.pullMat(destination)

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

Usage in Icy

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