Enum ChamferWeights

java.lang.Object

java.lang.Enum<ChamferWeights>

inra.ijpb.binary.ChamferWeights

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<ChamferWeights>, java.lang.constant.Constable

@Deprecated
public enum ChamferWeights
extends java.lang.Enum<ChamferWeights>

Deprecated.

replaced by inra.ijpb.binary.distmap.ChamferMask2D (since 1.5.0)

A pre-defined set of weights that can be used to compute distance transform using chamfer approximations of Euclidean metric.

Provides methods to access weight values either as float array or as short array.

Example of use:

        short[] shortWeights = ChamferWeights.CHESSKNIGHT.getShortWeights();
        boolean normalize = true;
        DistanceTransform dt = new DistanceTransform5x5Short(shortWeights, normalize);
        ImageProcessor result = dt.distanceMap(inputImage);
        // or:
        ImagePlus resultPlus = BinaryImages.distanceMap(imagePlus, shortWeights, normalize);
