Class ChamferLabelDilation2DShort

java.lang.Object
inra.ijpb.algo.AlgoStub
inra.ijpb.label.filter.ChamferLabelDilation2DShort
All Implemented Interfaces:
Algo
public class ChamferLabelDilation2DShort
extends AlgoStub
Apply a dilation by a specified radius to each label of a label map by constraining the dilation. Labels can not dilate over existing labels. Can be applied to label map encoded with 8 or 16 bits integers, or 32 bit floats.

      public ChamferLabelDilation2DShort​(ChamferMask2D mask, double radius)
      Creates a new image processor for dilating labels using the specified chamfer mask, using 16-bits integer computation.
      Parameters:
      mask - the Chamfer mask to use.
      radius - the radius of dilation of labels. In practice, the distance is propagated up to radius + 0.5.

    • process

      public ij.process.ImageProcessor process​(ij.process.ImageProcessor labelImage)
      Computes dilation of labels within label image by a specified radius. Labels can not dilate over existing labels. The function returns a new ImageProcessor the same size and the same type as the input, with values greater than or equal to zero.
      Parameters:
      labelImage - the original label map
      Returns:
      a new label image where each label is dilated over background pixels.
