WitrynaSkeletonization, also called thinning, is an important pre-processing step in computer vision and image pro-cessing tasks such as shape analysis and vectorization. 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. 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.
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. 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 ...

Introduction As a digital image processing technique, thinning has be-en around for many years. Thinning (also termed skele-tonization) is an image pre-processing technique that is 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:
