This paper presents the powerful ability of the neural network

and puts forward a new structure of the network in edge detection. On the basis of the understanding of Marr algorithm

the characteristics of Marr are taken great consideration into the structure of the network so as to improve the performance of algorithm. Meanwhile

under different noisy environment

among different algorithms in edge detection

comparative analyses are made to reveal that new method owns the powerful ability of anti noise

and that more applications are done well in the robot vision.
