Structuring Elements

Description

getStructuringElement is a convenience function to create structuring elements with defined shapes that can be used to filter images with filter2D.

Usage

getStructuringElement(
  k_shape = "rectangle",
  k_height = 5,
  k_width = 5,
  anchor = c(-1, -1)
)

Arguments

`k_shape`	A string corresponding to the shape of the structuring element. Valid kernel shapes are: "rectangle" (the default): "cross" "ellipse"
`k_height`	The half-height in pixels of the structuring element.
`k_width`	The half-width in pixels of the structuring element.
`anchor`	A 2-element numeric vector defining the anchor position within the cross-shaped structuring element. The default value (−1,−1) means that the anchor is at the center. Note that only the shape of a cross-shaped kernel depends on the anchor position.
