"WitrynaMorphological thinning. Morphological thinning, implemented in the thin function, works on the same principle as skeletonize: remove pixels from the borders at each iteration until none can be removed without altering the connectivity.The different rules of removal can speed up skeletonization and result in different final skeletons.

WitrynaExplaining the algorithm: It is so fast because most of the thinning is done by OpenCV using morphology, the rest is single passage done by hand. Current state: At the current implementation the thinning of the example image is done in less than 1.4s without showing the images and about 1.6s showing the images. Details of the input image: 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.
