      public ChamferLabelErosion2DShort​(ChamferMask2D mask, double radius)
      Creates a new operator for erosion of label images based on Chamfer masks. The principle is to compute for each non-zero pixel (label), the distance to the nearest background pixel, and to apply a threshold on this distance map.
      Parameters:
      mask - the Chamfer mask use to propagate distances
      radius - the radius used to compute erosion from distance map.

    • process

      public ij.process.ImageProcessor process​(ij.process.ImageProcessor image)
      Apply morphological erosion of the labels within the specified input image.
      Parameters:
      image - the label map to erode
      Returns:
      the result of erosion.
