Delation or Erosion of an image
this function performs delation or erosion to a 2- or 3- dimensional image
delationErosion(image, Filter, method = "delation", threads = 1)
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 ) |
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.
a matrix or 3-dimensional array
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')Please choose more modern alternatives, such as Google Chrome or Mozilla Firefox.
