delationErosion: Delation or Erosion of an image

Description

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

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 )

Value

a matrix or 3-dimensional array

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.

Examples

# NOT RUN {
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')

# }
