Class ExpandLabelsPlugin

java.lang.Object

inra.ijpb.plugins.ExpandLabelsPlugin

All Implemented Interfaces:

ij.plugin.PlugIn

public class ExpandLabelsPlugin
extends Object
implements ij.plugin.PlugIn

Creates a new image larger than the original one, and copies each label identically but shifted by a given dilation coefficient. This results in 2D or 3D images with fewer labels touching each other, making them easier to visualize.

The idea is to transform a label image in the following way:

                  1 1 1 0 0 0 0 0
 1 1 1 0 2 2      1 1 1 0 0 0 2 2
 1 1 1 0 2 2      0 0 0 0 0 0 2 2
 0 0 0 0 2 2  =>  0 0 0 0 0 0 2 2
 3 3 3 0 2 2      0 0 0 0 0 0 2 2     
 3 3 3 0 2 2      3 3 3 0 0 0 2 2
                  3 3 3 0 0 0 0 0
