Generates an image or structuring element of a given size

:Algorithms:


  - *diamond*

    Generates a diamond-shaped binary structuring element.



    A pixel is part of the neighborhood if the city block/Manhattan distance between it and the center of theneighborhood is no greater than radius.

    **size:**
      Radius of the disk


  - *disk*

    Generates an circular binary structuring element

    **size:**
      Radius of the disk


  - *empty*

    Generates an empty image of a given size

    **width:**
      Width of generated image

    **height:**
      Height of generated image

    **channels:**
      Number of channels in generated image

    **k:**
      Value for all pixels in all channels


  - *gaussian*

    Generates an elliptical Gaussian from the given variance matrix.

    **width:**
      Width of rectangle

    **height:**
      Height of rectangle

    **sigma-x:**
      Variation along first axis before rotation

    **sigma-y:**
      Variation along first axis before rotation

    **rotation:**
      Rotation given in radians

    **scale:**
      Multiplier for output

    **x:**
      Center point along x axis

    **y:**
      Center point along y axis

    **p:**
      Super-gaussian exponent (default 1)


  - *octagon*

    Generates an octagon-shaped binary structuring element.

    **size:**
      Size of horizontal/vertial parts of the octagon

    **other size:**
      Size of diagonal parts of the octagon


  - *rectangle*

    Generates a rectangle-shaped binary structuring element.

    **width:**
      Width of rectangle

    **height:**
      Height of rectangle


  - *square*

    Generates a square-shaped binary structuring element.

    **size:**
      Size of the square


  - *star*

    Generates a star-shaped binary structuring element.

    The star has 8 vertices and is an overlap of a square of size 2n + 1 with its 45 degree rotated version. The slanted sides are 45 or 135 degrees to the horizontal axis.

    **size:**
      Size "N" of the square
