excludeLabelsWithValuesWithinRange

This operation removes labels from a labelmap and renumbers the remaining labels.

Hand over a vector of values and a range specifying which labels with which values are eliminated.

Categories: Filter, Measurements, Labels

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_excludeLabelsWithValuesWithinRange(Image values_vector, Image label_map_input, Image label_map_destination, Number minimum_value_range, Number maximum_value_range);

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 values_vector = clij2.push(values_vectorImagePlus);
ClearCLBuffer label_map_input = clij2.push(label_map_inputImagePlus);
label_map_destination = clij2.create(values_vector);
float minimum_value_range = 1.0;
float maximum_value_range = 2.0;

// Execute operation on GPU
clij2.excludeLabelsWithValuesWithinRange(values_vector, label_map_input, label_map_destination, minimum_value_range, maximum_value_range);

// show result
label_map_destinationImagePlus = clij2.pull(label_map_destination);
label_map_destinationImagePlus.show();

// cleanup memory on GPU
clij2.release(values_vector);
clij2.release(label_map_input);
clij2.release(label_map_destination);

Matlab

% init CLIJ and GPU
clij2 = init_clatlab();

% get input parameters
values_vector = clij2.pushMat(values_vector_matrix);
label_map_input = clij2.pushMat(label_map_input_matrix);
label_map_destination = clij2.create(values_vector);
minimum_value_range = 1.0;
maximum_value_range = 2.0;

% Execute operation on GPU
clij2.excludeLabelsWithValuesWithinRange(values_vector, label_map_input, label_map_destination, minimum_value_range, maximum_value_range);

% show result
label_map_destination = clij2.pullMat(label_map_destination)

% cleanup memory on GPU
clij2.release(values_vector);
clij2.release(label_map_input);
clij2.release(label_map_destination);

Icy JavaScript

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

clij2 = CLICY.getInstance();

// get input parameters
values_vector_sequence = getSequence();
values_vector = clij2.pushSequence(values_vector_sequence);
label_map_input_sequence = getSequence();
label_map_input = clij2.pushSequence(label_map_input_sequence);
label_map_destination = clij2.create(values_vector);
minimum_value_range = 1.0;
maximum_value_range = 2.0;

// Execute operation on GPU
clij2.excludeLabelsWithValuesWithinRange(values_vector, label_map_input, label_map_destination, minimum_value_range, maximum_value_range);

// show result
label_map_destination_sequence = clij2.pullSequence(label_map_destination)
Icy.addSequence(label_map_destination_sequence);
// cleanup memory on GPU
clij2.release(values_vector);
clij2.release(label_map_input);
clij2.release(label_map_destination);
