Order Independence in Binary 2D Homotopic Thinning
This paper investigates binary homotopic 2D thinning in view of its independence of the order of processing image pixels. Pixel removal conditions are provided leading to an order independent thinning. They are introduced for various types of connectivity. Two kinds of pixels to be removed are considered: simple and b-simple. Use of each of those pixels yields to different types of order independent thinnings: homotopic marking and local-SKIZ.
