Image thinning

Witryna5 sty 2024 · Thinning algorithms works by selective deletion of object pixels along the image until it becomes one pixel width. The implementation of thinning algorithm started with medial axis transformation [3, 4].Hilditch algorithm [] is mainly used to thin the image edges.The algorithm checks all the pixels and decides to change a foreground … 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.
