Web4 de dez. de 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.
