Generates an image or structuring element of a given size

Documentation

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
