affineTransform3D

By Robert Haase based on work by Martin Weigert

Applies an affine transform to a 3D image.

The transform describes how coordinates in the target image are transformed to coordinates in the source image. This may appear unintuitive and will be changed in the next major release. The replacement affineTransform (currently part of CLIJx) will apply inverted transforms compared to this operation. Individual transforms must be separated by spaces.

Parameters

source : Image The input image to be processed. destination : Image The output image where results are written into. transform : String A space-separated list of individual transforms. Syntrax see below.

Supported transforms:

Example transform: transform = “-center scale=2 rotate=45 center”;

Category: Transformations

Availability: Available in Fiji by activating the update sites clij and clij2. This function is part of clij2_-2.5.0.1.jar.

Usage in ImageJ macro

Ext.CLIJ2_affineTransform3D(Image source, Image destination, String transform);

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);
// Execute operation on GPU
clij2.affineTransform3D(source, destination, transform);
// 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);
% Execute operation on GPU
clij2.affineTransform3D(source, destination, transform);
% 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);
// Execute operation on GPU
clij2.affineTransform3D(source, destination, transform);
// show result
destination_sequence = clij2.pullSequence(destination)
Icy.addSequence(destination_sequence);
// cleanup memory on GPU
clij2.release(source);
clij2.release(destination);
clEsperanto Python (experimental)
import pyclesperanto_prototype as cle

cle.affine_transform(source, destination, transform)
