All Implemented Interfaces:
Algo, GeodesicDistanceTransform
public class GeodesicDistanceTransformShortHybrid
extends AlgoStub
implements GeodesicDistanceTransform
Computation of geodesic distances based on a chamfer mask using short integer array for storing result. The maximum propagated distance is limited to Short.MAX_VALUE. All computations are performed using integers, results are stored as shorts.

    • 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 ShortProcessor 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
