Thinning is the dual of thickening, i.e. thickening the foreground is equivalent to thinning the background. Guidelines for Use One of the most common uses of thinning is to reduce the thresholded output of an edge detector such as the Sobel operator , to lines of a single pixel thickness, while preserving the full length of those lines ( i.e ...

    In this series of OpenCV Python Examples, you will start to write Python programs to perform basic operations in Image Processing like reading an image, resizing an image, extracting the different color channels of the image and also working around with these color channels. 1. You don't have to rebuild to use it. You can simply pip install contrib with: pip install opencv-contrib-python . Then you can simply use zhang-suen thinning implementation like this: image = cv2.imread ("opencv.png") thinned = cv2.ximgproc.thinning (cv2.cvtColor (image, cv2.COLOR_RGB2GRAY)) Debian bug tracking system. Debian has a bug tracking system (BTS) in which we file details of bugs reported by users and developers. Each bug is given a number, and is kept on file until it is marked as having been dealt with. Mat_ is a thin template wrapper over the Mat class. It doesn't contain any extra data fields in addition to what is available with the Mat object. In fact, references to the two classes (Mat and Mat_) can be converted to each other.

The function transforms a binary blob image into a skeletized form using the technique of Zhang-Suen. Now, let’s discuss how to implement this using OpenCV-Python. Now, let’s discuss thinning using hit-or-miss transform. Thinning of set A by SE B can be expressed in terms of hit-or-miss transform as. This means we remove all those pixels whose neighborhood exactly matches the pixels in the SE. ◆ thinning () #include < opencv2/ximgproc.hpp > Applies a binary blob thinning operation, to achieve a skeletization of the input image.
