  • Method Details

    • fromDiameter

      public static final LinearDepthStrel3D fromDiameter​(int diam)
      Creates a new line-shape structuring element with the specified diameter (equal to the length of the line).
      Parameters:
      diam - the length of the line along the Z direction
      Returns:
      a new linear structuring element

    • fromRadius

      public static final LinearDepthStrel3D fromRadius​(int radius)
      Creates a new line-shape structuring element with the specified radius (such that orthogonal diameter equals 2*radius+1).
      Parameters:

      Returns:
      a new linear structuring element

    • inPlaceDilation

      public void inPlaceDilation​(ij.ImageStack stack)
      Description copied from interface: InPlaceStrel3D
      Performs dilation of the stack given as argument, and stores the result in the same image.
      Parameters:
      stack - the input image stack to dilate

    • inPlaceErosion

      public void inPlaceErosion​(ij.ImageStack stack)
      Description copied from interface: InPlaceStrel3D
      Performs erosion of the image given as argument, and stores the result in the same image.
      Parameters:
