Computes the distance map transform of a binary image. The distance map is a matrix which contains for each pixel the distance to its nearest background pixel.
Value
An Image object or an array, with pixels containing the distances
to the nearest background points
Examples
library(pliman)
img <- image_pliman("soybean_touch.jpg")
binary <- image_binary(img, "B")[[1]]
wts <- dist_transform(binary)
range(wts)
#> [1] 0 29
