delationErosion: Delation or Erosion of an image

In OpenImageR: An Image Processing Toolkit

Delation or Erosion of an image

Description

'r lifecycle::badge("deprecated")'

This function was deprecated because I realized that the name of the function does not correspond to the name of the algorithm (delation -> dilation)

this function performs delation or erosion to a 2- or 3- dimensional image

Usage

delationErosion(image, Filter, method = "delation", threads = 1)

Arguments

image	a matrix, data frame or 3-dimensional array where the third dimension is equal to 3
Filter	a vector specifying the dimensions of the kernel, which will be used to perform either delation or erosion, such as c(3,3)
method	one of 'delation', 'erosion'
threads	number of cores to run in parallel ( > 1 should be used if image high dimensional )

Details

This function utilizes a kernel to perform delation or erosion. The first value of the vector indicates the number of rows of the kernel, whereas the second value indicates the number of columns.

Value

a matrix or 3-dimensional array where the third dimension is equal to 3

Examples

path = system.file("tmp_images", "1.png", package = "OpenImageR")

image = readImage(path)

res_delate = delationErosion(image, Filter = c(3,3), method = 'delation')

res_erode = delationErosion(image, Filter = c(5,5), method = 'erosion')

# ->

res_dilate = dilationErosion(image, Filter = c(3,3), method = 'dilation')

res_erode = dilationErosion(image, Filter = c(5,5), method = 'erosion')
