【Abstract】 The principle of the back propagation network(BPN) is introducod and the BPN is applied to identification of the character of the engineering drawings. How to determine the network structure and the number of the processing elements and work parameters and how to select and divide the example of character image are introduced. The results of the experiment show BPN can be applied to recognize character of engineering drawings.更多还原
