applyVectorField2D

Deforms an image according to distances provided in the given vector images.

It is recommended to use 32-bit images for input, output and vector images.

Parameters

source : Image The input image to be processed. vector_x : Image Pixels in this image describe the distance in X direction pixels should be shifted during warping. vector_y : Image Pixels in this image describe the distance in Y direction pixels should be shifted during warping. destination : Image The output image where results are written into.

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.

applyVectorField2D often follows after

affineTransform2D (2)

applyVectorField2D is often followed by

copySlice (1)

Usage in ImageJ macro

Ext.CLIJ2_applyVectorField2D(Image source, Image vector_x, Image vector_y, Image destination);

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);
ClearCLBuffer vector_x = clij2.push(vector_xImagePlus);
ClearCLBuffer vector_y = clij2.push(vector_yImagePlus);
destination = clij2.create(source);

// Execute operation on GPU
clij2.applyVectorField2D(source, vector_x, vector_y, destination);

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

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

Matlab

% init CLIJ and GPU
clij2 = init_clatlab();

% get input parameters
source = clij2.pushMat(source_matrix);
vector_x = clij2.pushMat(vector_x_matrix);
vector_y = clij2.pushMat(vector_y_matrix);
destination = clij2.create(source);

% Execute operation on GPU
clij2.applyVectorField2D(source, vector_x, vector_y, destination);

% show result
destination = clij2.pullMat(destination)

% cleanup memory on GPU
clij2.release(source);
clij2.release(vector_x);
clij2.release(vector_y);
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);
vector_x_sequence = getSequence();
vector_x = clij2.pushSequence(vector_x_sequence);
vector_y_sequence = getSequence();
vector_y = clij2.pushSequence(vector_y_sequence);
destination = clij2.create(source);

// Execute operation on GPU
clij2.applyVectorField2D(source, vector_x, vector_y, destination);

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