resample

Resamples an image with given size factors using an affine transform.

Category: Transformations

Availability: Available in Fiji by activating the update sites clij and clij2. This function is part of clij2_-2.2.0.19.jar.

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);
float factor_x = 1.0;
float factor_y = 2.0;
float factor_z = 3.0;
boolean linear_interpolation = true;
// Execute operation on GPU
clij2.resample(source, destination, factor_x, factor_y, factor_z, linear_interpolation);
// 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);
factor_x = 1.0;
factor_y = 2.0;
factor_z = 3.0;
linear_interpolation = true;
% Execute operation on GPU
clij2.resample(source, destination, factor_x, factor_y, factor_z, linear_interpolation);
% 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();
