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
