Package inra.ijpb.binary.geodesic

Class GeodesicDiameterShort

java.lang.Object
inra.ijpb.algo.AlgoStub
inra.ijpb.binary.geodesic.GeodesicDiameterShort
All Implemented Interfaces:
Algo, GeodesicDiameter
@Deprecated
public class GeodesicDiameterShort
extends AlgoStub
implements GeodesicDiameter
Deprecated.
since 1.3.5, use inra.ijpb.measure.region2d.GeodesicDiameter instead
Computes geodesic diameter of a set of labeled particles or regions, using integer values coded as short (16 bits) for propagating chamfer distances. This version uses optimized algorithm, that propagates distances of all particles during each pass. This reduces computation overhead due to iteration over particles.

Example of use: 


	GeodesicDiameterShort gd = new GeodesicDiameterShort(ChamferWeights.CHESSKNIGHT);
	ResultsTable table = gd.analyseImage(inputLabelImage);
	table.show("Geodesic Diameter");

    • analyzeImage

      public ij.measure.ResultsTable analyzeImage​(ij.process.ImageProcessor labelImage)
      Deprecated.
      Computes the geodesic diameter of each particle within the given label image.
      Specified by:
      analyzeImage in interface GeodesicDiameter
      Parameters:
      labelImage - a label image, containing either the label of a particle or region, or zero for background
      Returns:
      a ResultsTable containing for each label the geodesic diameter of the corresponding particle

    • longestGeodesicPaths

      public java.util.Map<java.lang.Integer,​java.util.List<java.awt.Point>> longestGeodesicPaths()
      Deprecated.
      Computes the geodesic path of each particle within the given label image. Assumes the geodesic distance map has already been computed after a call to the "analyzeImage" method.
      Returns:
      A map that associate to each integer label the list of positions that constitutes the geodesic path
