Class DistanceTransform2D

java.lang.Object
  io.loader.load2D.DistanceTransform2D

public class DistanceTransform2D
extends java.lang.Object

get the distance transform DT of a binary shape image. The distance transform is a function that assigns for each pixel p(x,y) inside an object the minimal distance to the boundary.

In this project, a distance transform is stored as a simple two-dimensional array distanceTransform, where the distance of a pixel p(x,y) can be looked up at distanceTransform[x][y].

Method Detail

getDistanceTransform

public static double[][] getDistanceTransform(ij.ImagePlus imp)

Get the specified image's distance transform. Internally, the ImageJ plugin "Distance Map" is used for that purpose. The distance transform is stored as a simple two-dimensional array distanceTransform, where the distance of a pixel p(x,y) can be looked up at distanceTransform[x][y].

Parameters:

imp - - the binary image to get the distance transform for.

Returns:

distance map as simple double array
