Abstract
The work presented in this paper focuses on recognition of isolated handwritten numerals in Devanagari and Gurumukhi script. The proposed work uses four feature extraction methods like Zoning density, Projection histograms, Distance profiles and Background Directional Distribution(BDD). On the basis of these four types of features we have formed 10 feature vectors using different combinations of four basic features. This work uses Support Vector machines(SVM) for the classification of numerals. A total of 2000 samples of numerals are taken for Gurumukhi and Devanagari and we have attain a maximum recognition accuracy of 99. 6% in case of Gurumukhi Numeral recognition and 99% for Devanagri Numeral recognition. In addition to SVM classifier , we have also used two similarity based classifiers Euclidean distance and Square chord distance for the classification purpose. With Euclidean distance ,a recognition accuracy of 99% and 91. 67% is obtained for Gurumukhi and Devanagri numarals respectively. Similarly with Square Chord distance accuracy of 95. 33% and 81. 67% is obtained for Gurumukhi and devanagri numerals respectively
