Neuro-fuzzy techniques in the recognition of written Arabic characters

A new method for recognition of handwritten Arabic characters is presented. Characters are recognized by detecting their geometrical features and by conducting some discriminatory tests on their projection data. Most of the chosen features are easy to extract. Some of the features which are not so obvious are inferred from measurements. Fuzzy logic is used to model the uncertainties in the relationships between the variables. The 28 isolated letters of the Arabic alphabet are then classified by a feedforward neural network. The simulation results show the recognition rate is high though only a limited number of features has been involved.
