Class DistanceTransform3x3Short

java.lang.Object
inra.ijpb.algo.AlgoStub
inra.ijpb.binary.distmap.DistanceTransform3x3Short
All Implemented Interfaces:
Algo, DistanceTransform
@Deprecated
public class DistanceTransform3x3Short
extends AlgoStub
implements DistanceTransform
Deprecated.
replaced by ChamferDistanceTransform2DShort (since 1.5.0)
Computes Chamfer distances in a 3x3 neighborhood using ShortProcessor object for storing result.

Example of use: 


	short[] shortWeights = ChamferWeights.BORGEFORS.getShortWeights();
	boolean normalize = true;
	DistanceTransform dt = new DistanceTransform3x3Short(shortWeights, normalize);
	ImageProcessor result = dt.distanceMap(inputImage);
	// or:
	ImagePlus resultPlus = BinaryImages.distanceMap(imagePlus, shortWeights, normalize);

    • distanceMap

      public ij.process.ShortProcessor distanceMap​(ij.process.ImageProcessor labelImage)
      Deprecated.
      Computes the distance map of the distance to the nearest pixel with a different value. The function returns a new short processor the same size as the input, with values greater or equal to zero.
      Specified by:
      distanceMap in interface DistanceTransform
      Parameters:
      labelImage - a label image with black pixels (0) as foreground
      Returns:
      a new instance of ShortProcessor containing:
      • 0 for each background pixel
      • the (strictly positive) distance to the nearest background pixel otherwise
