What is Sobel in Python?

Using the sobel operation, you can detect the edges of an image in both horizontal and vertical directions. You can apply sobel operation on an image using the method sobel(). Following is the syntax of this method − Sobel(src, dst, ddepth, dx, dy)

What is Sobel operator used for?

The Sobel operator performs a 2-D spatial gradient measurement on an image and so emphasizes regions of high spatial frequency that correspond to edges. Typically it is used to find the approximate absolute gradient magnitude at each point in an input grayscale image.

What is Sobel in cv2?

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.

Why is Sobel better than canny?

The main advantages of the Sobel operator are that it is simple and more time-efficient. However, the edges are rough. On the other hand, the Canny technique produces smoother edges due to the implementation of Non-maxima suppression and thresholding.
