  • Constructor Details

    • OrientedLineStrel

      public OrientedLineStrel​(double length, double angleInDegrees)
      Creates an new instance of linear structuring element. The number of pixels composing the line may differ from the specified length due to rounding effects.
      Parameters:
      length - the (approximate) length of the structuring element.
      angleInDegrees - the angle with the horizontal of the structuring element

  • Method Details

    • getSize

      public int[] getSize()
      Returns the size of the structuring element, as an array of size in each direction.
      Specified by:
      getSize in interface Strel
      Specified by:
      getSize in interface Strel3D
      Returns:
      the size of the structuring element

    • getMask

      public int[][] getMask()
      Returns the structuring element as a mask. Each value is either 0 or 255.
      Specified by:
      getMask in interface Strel
      Returns:
      the mask of the structuring element

    • getOffset

      public int[] getOffset()
      Returns the offset in the mask.
      Specified by:
      getOffset in interface Strel
      Specified by:
      getOffset in interface Strel3D
      Returns:
      the offset in the mask

    • getShifts

      public int[][] getShifts()
      Returns the structuring element as a set of shifts.
      Specified by:
      getShifts in interface Strel
      Returns:
      a set of shifts

    • dilation

      public ij.process.ImageProcessor dilation​(ij.process.ImageProcessor image)
      Description copied from interface: Strel
      Performs a morphological dilation of the input image with this structuring element, and returns the result in a new ImageProcessor.
      Specified by:
      dilation in interface Strel
      Parameters:
      image - the input image
      Returns:
      the result of dilation with this structuring element
      See Also:
      Strel.erosion(ij.process.ImageProcessor), Strel.closing(ij.process.ImageProcessor), Strel.opening(ij.process.ImageProcessor)

    • erosion

      public ij.process.ImageProcessor erosion​(ij.process.ImageProcessor image)
      Description copied from interface: Strel
      Performs an morphological erosion of the input image with this structuring element, and returns the result in a new ImageProcessor.
      Specified by:
      erosion in interface Strel
      Parameters:
      image - the input image
      Returns:
      the result of erosion with this structuring element

    • closing

      public ij.process.ImageProcessor closing​(ij.process.ImageProcessor image)
      Description copied from interface: Strel
      Performs a morphological closing of the input image with this structuring element, and returns the result in a new ImageProcessor. The closing is equivalent in performing a dilation followed by an erosion with the reversed structuring element.
