WitrynaIn Thickening a part of boundary of the background is added to the object. For a image A and a Composite structuring element B = (B1,B2),Thickening can be defined as, ʘ A ʘ B = A U ( A ⊗ B) Thinning and Thickening are dual operations.i.e., ʘ Ø ( A ʘ B) C = A C Ø B; Thinning and Thickening transformations are very often used sequentially, 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.

Witryna2.4. Grayscale 3D Image Thinning True grayscale thinning algorithms are rare; most applications assume that an initial segmentation step will extract an accurate foreground set for binary thin-ning. A few thinning algorithms, however, do consider grayscale information. One approach is to sample a limited number of ‚-sections, then add ... 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.
