@Deprecated
public enum ChamferWeights3D
extends java.lang.Enum<ChamferWeights3D>
Deprecated.
replaced by inra.ijpb.binary.distmap.ChamferMask2D (since 1.5.0)

A pre-defined set of weights that can be used to compute 3D 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: 


 float[] floatWeights = ChamferWeights3D.BORGEFORS.getFloatWeights();
 boolean normalize = true;
 DistanceTransform3D dt = new DistanceTransform3DFloat(floatWeights, normalize);
 ImageStack result = dt.distanceMap(inputStack);

      Deprecated.
      Computes the collection of weighted offsets corresponding to a scan of the voxels in a 3D image in the forward direction. The number of offsets depends on the number of weights (3 or 4 weights are required):
      • the first weight corresponds to a step in the orthogonal directions (three offsets).
      • the second weight corresponds to a step in a diagonal direction within a plane (six offsets).
      • the third weight corresponds to a step in a cube-diagonal direction (four offsets).
      • the (optional) fourth weight corresponds to a step in a permutation of the (2,1,1) vector (twelve offsets).
      Parameters:
      weights - an array of (short) weights, corresponding to orthogonal, diagonal, and optionally more neighbors.
      Returns:
      a collection of offset encapsulating the shift in x, y and z directions, and the associated weight.
