public class PrewittEdgeDetector : XYGradientEdgeDetector
Remarks

Prewitt edge processing involves the application (via convolution) of a 3x3 kernel that approximates the local derivatives in the X and Y directions. The Prewitt kernel places equal weight to all values of the kernel. The magnitude of the local derivative is assumed to be proportional to the local edge strength. To view the local edge strength, generate an image of the edge magnitude. Alternatively, images of the individual gradients (in both the X and Y directions) can be generated.

See XYGradientEdgeDetector (the base class for the Prewitt edge detector) for more information.
