Class GeodesicDistanceTransformFloat

java.lang.Object
inra.ijpb.algo.AlgoStub
inra.ijpb.binary.geodesic.GeodesicDistanceTransformFloat
All Implemented Interfaces:
Algo, GeodesicDistanceTransform
public class GeodesicDistanceTransformFloat
extends AlgoStub
implements GeodesicDistanceTransform
Computation of Chamfer geodesic distances using floating point array for storing result. This implementation is based on iteration of forward-backward passes, until idempotence. The "hybrid" implementation is usually more efficient for complex images.

  • Method Details

    • geodesicDistanceMap

      public ij.process.ImageProcessor geodesicDistanceMap​(ij.process.ImageProcessor marker, ij.process.ImageProcessor labelImage)
      Computes the geodesic distance function for each pixel in mask label image, using the given binary marker image. Mask and marker should be ImageProcessor the same size and containing integer values. The function returns a new FloatProcessor the same size as the input, with values greater or equal to zero.
      Specified by:
      geodesicDistanceMap in interface GeodesicDistanceTransform
      Parameters:
      marker - the binary marker image
      labelImage - the label image used as mask
      Returns:
      the geodesic distance map from the marker image within each label of the mask
