In this tutorial, you will learn about image gradients and how to compute Sobel gradients and Scharr gradients using OpenCV’s cv2.Sobel function. Image gradients are a fundamental building block of many computer vision and image processing routines. We use gradients…

Today’s post is a followup to a previous (extremely popular) article on detecting barcodes in images using Python and OpenCV. In the previous post we explored how to detect and find barcodes in images. But today we are going to…
