pointIndexListToTouchMatrix

Takes a list of point indices to generate a touch matrix (a.k.a. adjacency graph matrix) out of it.

The list hasa dimensionality of m*n for the points 1… m (0 a.k.a. background is not in this list). In the n rows, there are indices to points which should be connected.

Parameters

indexlist : Image matrix_destination : Image

Category: Graphs

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_pointIndexListToTouchMatrix(Image indexlist, Image matrix_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 indexlist = clij2.push(indexlistImagePlus);
matrix_destination = clij2.create(indexlist);

// Execute operation on GPU
clij2.pointIndexListToTouchMatrix(indexlist, matrix_destination);

// show result
matrix_destinationImagePlus = clij2.pull(matrix_destination);
matrix_destinationImagePlus.show();

// cleanup memory on GPU
clij2.release(indexlist);
clij2.release(matrix_destination);

Matlab

% init CLIJ and GPU
clij2 = init_clatlab();

% get input parameters
indexlist = clij2.pushMat(indexlist_matrix);
matrix_destination = clij2.create(indexlist);

% Execute operation on GPU
clij2.pointIndexListToTouchMatrix(indexlist, matrix_destination);

% show result
matrix_destination = clij2.pullMat(matrix_destination)

% cleanup memory on GPU
clij2.release(indexlist);
clij2.release(matrix_destination);

Icy JavaScript

// init CLIJ and GPU
importClass(net.haesleinhuepf.clicy.CLICY);
importClass(Packages.icy.main.Icy);

clij2 = CLICY.getInstance();

// get input parameters
indexlist_sequence = getSequence();
indexlist = clij2.pushSequence(indexlist_sequence);
matrix_destination = clij2.create(indexlist);

// Execute operation on GPU
clij2.pointIndexListToTouchMatrix(indexlist, matrix_destination);

// show result
matrix_destination_sequence = clij2.pullSequence(matrix_destination)
Icy.addSequence(matrix_destination_sequence);
// cleanup memory on GPU
clij2.release(indexlist);
clij2.release(matrix_destination);
