| Abstract: | Based on a review of the features of visual information processing of biological system and a comparision of it with wavelet transform , a new ANN architecture and algorithm is devised for the recogition of hand -written numerals . The Generalized Energy Constrained Method is used to improve its performance further . The model is shown to have fairly good generalization and classification capability by computer simulation . |
