It is a morphological process that generates a skeleton from an input image. Many thinning algorithms have been proposed, but accurate and fast algorithms are still in demand.

WitrynaThis paper investigates the skeletonization problem using parallel thinning techniques and proposes a new one-pass parallel asymmetric thinning algorithm (OPATA 8).Wu and Tsai presented a one-pass parallel asymmetric thinning algorithm (OPATA 4) that implemented 4-distance, or city block distance, skeletonization.However, city block … WitrynaThinning is an important preprocessing step for many image analysis operations. The goal of this paper is to present and evaluate two parallel thinning algorithms. The authors define these algorithms over binary-valued images digitized in a rectangular tessellation, as two-subiteration algorithms restricted to 3 × 3 thinning operators. notes and outlines

Witryna4 gru 2014 · Thinning is the operation that takes a binary image and contracts the foreground until only single-pixel wide lines remain. It is also known as skeletonization. This package implements the thinning algorithm by Guo and Hall [1] for Numpy arrays. It is thus compatible with OpenCV. The algorithm is implemented in C and fairly fast. Thinning is the transformation of a digital image into a simplified, but topologically equivalent image. It is a type of topological skeleton, but computed using mathematical morphology operators.
