thinning: Thinning and skeletonization

In tkatsuki/dipr: Digital Image Processing with R

Description

These functions are for thinning, skeletonization, and analysis of thinned binary images. skeletonize skeletonizes a binary image using morphological operations. Topology may not be preserved. thinning thins a binary image using a method of Gonzalez and Woods (see reference). Topology is preserved. ending detects end points from a thinned image. branch detects branch points from a thinned image. isolated detects isolated points from a thinned image. pruning prunes (removes branches) a thinned image.

branch(x)
isolated(x)
pruning(x, n = 20)

Arguments

img	A binary image of Image class or matrix.
n	Number of pixels to prune.
