Digital Image Processing using OpenCV (Python & C++) Highlights: In this post, we will learn what Sobel operator and an image gradient are. We will show how to calculate the horizontal and vertical edges as well as edges in general. What is the most important element in the image? Edges! See below. Tutorial Overview: What is the gradient? Finite difference. Discrete gradient. Sobel Operator. 1. What is the Gradient? Let’s talk about differential operators. When…
