The Sobel Operator is a discrete differentiation operator. It computes an approximation of the gradient of an image intensity function. The Sobel Operator combines Gaussian smoothing and differentiation. Formulation Assuming that the image to be operated is : We calculate two derivatives: Ver mais In this tutorial you will learn how to: 1. Use the OpenCV function Sobel()to calculate the derivatives from an image. 2. Use the OpenCV function Scharr()to calculate a more accurate derivative for a kernel of size Ver mais WebOPENCV & C++ TUTORIAL - 4 SOBEL OPERATOR Computer Vision Lab 696 subscribers Subscribe 1.7K views 1 year ago #sobel #opencv #edgedetection Sobel …
