WebThe Prewitt operator is used in image processing, particularly within edge detection algorithms. Technically, it is a discrete differentiation operator, computing an approximation of the gradient of the image intensity function. At each point in the image, the result of the Prewitt operator is either the corresponding gradient vector or the norm of this vector. WebJan 8, 2013 · OpenCV provides three types of gradient filters or High-pass filters, Sobel, Scharr and Laplacian. We will see each one of them. 1. Sobel and Scharr Derivatives. Sobel operators is a joint Gaussian smoothing plus differentiation operation, so it is more resistant to noise.
