Class DistanceTransform3DShort

java.lang.Object
inra.ijpb.algo.AlgoStub
inra.ijpb.binary.distmap.DistanceTransform3DShort
All Implemented Interfaces:
Algo, DistanceTransform3D
@Deprecated
public class DistanceTransform3DShort
extends AlgoStub
implements DistanceTransform3D
Deprecated.
replaced by ChamferDistanceTransform3DShort (since 1.5.0)
Computes Chamfer distances in a 3x3x3 neighborhood and storing result in 16-bits image. In practice, computations are done with integers, but result is stored in a 3D short image, thus requiring less memory than floating point.

    • distanceMap

      public ij.ImageStack distanceMap​(ij.ImageStack image)
      Deprecated.
      Computes the distance map from a 3D binary image. Distance is computed for each foreground (white) pixel, as the chamfer distance to the nearest background (black) pixel.
      Specified by:
      distanceMap in interface DistanceTransform3D
      Parameters:
      image - a 3D binary image with white pixels (255) as foreground
      Returns:
      a new 3D image containing:
      • 0 for each background pixel
      • the distance to the nearest background pixel otherwise
