  • Constructor Details

    • LinearVerticalStrel

      public LinearVerticalStrel​(int size)
      Creates a new vertical linear structuring element of a given size.
      Parameters:
      size - the number of pixels in this structuring element

    • LinearVerticalStrel

      public LinearVerticalStrel​(int size, int offset)
      Creates a new vertical linear structuring element of a given size and with a given offset.
      Parameters:
      size - the number of pixels in this structuring element
      offset - the position of the reference pixel (between 0 and size-1)

  • Method Details

    • fromDiameter

      public static final LinearVerticalStrel 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 Y direction
      Returns:
      a new linear structuring element

    • fromRadius

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

    • inPlaceDilation

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

    • inPlaceErosion

      public void inPlaceErosion​(ij.process.ImageProcessor image)
      Description copied from interface: InPlaceStrel
      Performs erosion of the image given as argument, and stores the result in the same image.
      Parameters:
      image - the input image to erode

    • getMask

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

    • getOffset

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

    • getShifts

      public int[][] getShifts()
      Description copied from interface: Strel
      Returns the structuring element as a set of shifts. The size of the result is N-by-2, 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

    • getSize

      public int[] getSize()
      Description copied from interface: Strel
      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

    • reverse

      public LinearVerticalStrel reverse()
      Returns a linear vertical line with same size and offset equal to size-offset-1.
      Returns:
      the reversed structuring element
