  • Method Details

    • fromRadius

      public static final BallStrel fromRadius​(double radius)
      Creates a structuring element with a spherical shape of the given radius.
      Parameters:
      radius - the radius of the structuring element, in pixels
      Returns:
      a new structuring element with ball shape and specified radius

    • fromDiameter

      public static final BallStrel fromDiameter​(double diam)
      Creates a structuring element with a spherical shape of the given diameter.
      Parameters:
      diam - the diameter of the ball, in pixels
      Returns:
      a new structuring element with ball shape and specified radius

    • getSize

      public int[] getSize()
      Description copied from interface: Strel3D
      Returns the size of the structuring element, as an array of size in each direction. The first index corresponds to the number of pixels in the x direction.
      Returns:
      the size of the structuring element

    • getMask3D

      public int[][][] getMask3D()
      Description copied from interface: Strel3D
      Returns the structuring element as a mask. Each value is either 0 or 255. The first index corresponds to the z position, the second index to the y direction, and the third one to the x position.
      Returns:
      the mask of the structuring element

    • getOffset

      public int[] getOffset()
      Description copied from interface: Strel3D
      Returns the offset in the mask for each direction. The first value corresponds to the shift in the x direction.
      Returns:
      the offset in the mask

    • getShifts3D

      public int[][] getShifts3D()
      Description copied from interface: Strel3D
      Returns the structuring element as a set of shifts. The size of the result is N-by-3, where N is the number of elements of the structuring element. The first value corresponds to the shift in the x direction.
      Returns:
      a set of shifts

    • reverse

      public Strel3D reverse()
      Description copied from interface: Strel3D
      Returns a reversed (i.e. symmetric wrt the origin) version of this structuring element. Implementations can return more specialized type depending on the implemented interfaces.
      Returns:
      the reversed structuring element

    • dilation

      public ij.ImageStack dilation​(ij.ImageStack image)
      Performs dilation with a ball structuring element by calling the ImageJ Filters3D.filter method, using Filters3D.MAX option.
      Specified by:

      Overrides:
      dilation in class AbstractStrel3D
      Parameters:
      image - the 3D stack to process
      Returns:
      the result of dilation with this structuring element

      Strel3D.getShifts3D(), AbstractStrel3D.erosion(ImageStack)

    • erosion

      public ij.ImageStack erosion​(ij.ImageStack image)
      Performs erosion with a ball structuring element by calling the ImageJ Filters3D.filter method, using Filters3D.MIN option.
      Specified by:
      erosion in interface Strel3D
      Overrides:
      erosion in class AbstractStrel3D
      Parameters:
      image - the 3D stack to process
      Returns:
      the result of erosion with this structuring element
