Generate Image

Generates an image or structuring element of a given size

Documentation

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
