This paper presents a proposed neural network based edge detection
algorithm. we have used artificial neural network system to decide about whether
each pixel is edge or not. First standard deviation values are computed for mask
(3*3), Then after training a neural network system to recognize structural patterns
(these pattern represents edges), it decides on each pixel if its edge or not. Finally
we have test the proposed method on different images. Experimental results show
the ability and high performance of proposed algorithm.
