WebIn this tutorial you will learn how to find a given configuration or pattern in a binary image by using the Hit-or-Miss transform (also known as Hit-and-Miss transform). This transform is also the basis of more advanced morphological operations such as thinning or pruning. We will use the OpenCV function cv::morphologyEx.
