Class GeodesicDiameterShort

java.lang.Object

inra.ijpb.algo.AlgoStub

inra.ijpb.binary.geodesic.GeodesicDiameterShort

All Implemented Interfaces:

Algo, GeodesicDiameter

Deprecated.

since 1.3.5, use inra.ijpb.measure.region2d.GeodesicDiameter instead

@Deprecated
public class GeodesicDiameterShort
extends AlgoStub
implements GeodesicDiameter

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");

Constructor Detail

GeodesicDiameterShort

public GeodesicDiameterShort(ChamferWeights chamferWeights)

Deprecated.

Creates a new geodesic diameter computation operator.

Parameters:

chamferWeights - an instance of ChamferWeights, which provides the float values used for propagating distances

GeodesicDiameterShort

public GeodesicDiameterShort(short[] weights)

Deprecated.

Creates a new geodesic diameter computation operator.

Parameters:

weights - the array of weights for orthogonal, diagonal, and eventually chess-knight moves neighbors

Method Detail

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 Map<Integer,List<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
