    Constructor Description
    OrientedLineStrel​(double length, double angleInDegrees)
    Creates an new instance of linear structuring element.

  • Method Summary

    Modifier and Type Method Description
    ij.process.ImageProcessor closing​(ij.process.ImageProcessor image)
    Performs a morphological closing on the input image, by applying first a dilation, then an erosion with the reversed structuring element.
    ij.process.ImageProcessor dilation​(ij.process.ImageProcessor image)
    Implements a default algorithm for dilation, that consists in iterating over the neighbors of each pixel to compute the maximum value.
    ij.process.ImageProcessor erosion​(ij.process.ImageProcessor image)
    Implements a default algorithm for erosion, that consists in iterating over the neighbors of each pixel to compute the minimum value.
    int[][] getMask()
    Returns the structuring element as a mask.
    int[] getOffset()
    Returns the offset in the mask.
    int[][] getShifts()
    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.process.ImageProcessor opening​(ij.process.ImageProcessor image)
    Performs a morphological opening on the input image, by applying first an erosion, then a dilation with the reversed structuring element.
    Strel reverse()
    Returns this structuring element, as oriented line structuring elements are symmetric by definition.

    • 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
