Class Reconstruction

java.lang.Object

inra.ijpb.morphology.Reconstruction

Direct Known Subclasses:

GeodesicReconstruction

public abstract class Reconstruction
extends Object

Morphological reconstruction for grayscale or binary images. Most algorithms works for any data type.

This class provides a collection of static methods for commonly used operations, such as border removal or holes filling.

Example of use:

 ImageProcessor mask = IJ.getImage().getProcessor();
 ImageProcessor marker = mask.createProcessor(mask.getWidth(), mask.getHeight());
 marker.set(20, 10, 255); 
 ImageProcessor rec = Reconstruction.reconstructByDilation(marker, mask, 4);
 ImagePlus res = new ImagePlus("Reconstruction", rec);
 res.show();
