WebWhen the weight at the central pixels, for both Prewitt templates, is doubled, this gives the famous Sobel edge-detection operator which, again, consists of two masks to determine the edge in vector form. The Sobel operator was the most popular edge-detection operator until the development of edge-detection techniques with a theoretical basis.
