Difference between sobel and prewitt
WebPrewitt Operator. Prewitt operator is used for edge detection in an image. It detects two types of edges. Edges are calculated by using difference between corresponding pixel intensities of an image. All the masks that are used for edge detection are also known as derivative masks.
