Package inra.ijpb.binary.distmap
Computations of distance maps on binary images, using chamfer distances (integer approximation of Euclidean distances).
Contains implementations for computation using shorts or float values, for 3x3 and 5x5 neighborhoods.
Example of use:
ChamferMask3D mask = ChamferMask3D.CHESSKNIGHT;
boolean normalize = true;
DistanceTransform dt = new ChamferDistanceTransform2DShort(mask, normalize);
ImageProcessor result = dt.distanceMap(inputImage);
// or:
ImagePlus resultPlus = BinaryImages.distanceMap(imagePlus, mask, false, normalize);
