Stochastic Edge Detection

\label{stochastic-edge-detection}
The basic idea of edge detection is to detect changes in intensity for the purpose of finding edges can be implemented by using first or second order derivatives [10]. This operation is implicitly interpreted as the masks or filter or the gradient operators. This work will consider two such operators: Roberts and Prewitt.
