  • Method Summary

    Modifier and Type Method Description
    ij.ImageStack closing​(ij.ImageStack image)
    Performs a morphological closing on the input stack, by applying first a dilation, then an erosion with the reversed structuring element.
    ij.ImageStack dilation​(ij.ImageStack image)
    Implements a default algorithm for dilation, that consists in iterating over the neighbors of each pixel to compute the maximum value.
    ij.ImageStack erosion​(ij.ImageStack image)
    Implements a default algorithm for erosion, that consists in iterating over the neighbors of each pixel to compute the minimum value.
    int[][][] getMask3D()
    Returns the structuring element as a mask.
    int[] getOffset()
    Returns the offset in the mask for each direction.
    int[][] getShifts3D()
    Returns the structuring element as a set of shifts.
    int[] getSize()
    Returns the size of the structuring element, as an array of size in each direction.
    ij.ImageStack opening​(ij.ImageStack image)
    Performs a morphological opening on the input stack, by applying first an erosion, then a dilation with the reversed structuring element.
    Strel3D reverse()
    Returns a reversed (i.e. symmetric wrt the origin) version of this structuring element.

  • Constructor Details

    • Cross3DStrel

      public Cross3DStrel()
      Create a new instance of this structuring element.

  • Method Details

    • 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)
      Description copied from class: AbstractStrel3D
      Implements a default algorithm for dilation, that consists in iterating over the neighbors of each pixel to compute the maximum value. The neighbors are obtained via the getShifts() method.
      Specified by:
      dilation in interface Strel3D
      Overrides:
      dilation in class AbstractStrel3D
      Parameters:
      image - the input image
      Returns:
      the result of dilation with this structuring element

    • erosion

      public ij.ImageStack erosion​(ij.ImageStack image)
      Description copied from class: AbstractStrel3D
      Implements a default algorithm for erosion, that consists in iterating over the neighbors of each pixel to compute the minimum value. The neighbors are obtained via the getShifts() method.
      Specified by:
      erosion in interface Strel3D
      Overrides:
      erosion in class AbstractStrel3D
      Parameters:
