| Abstract: | Handwritten digit recognition has wide application foreground in many domains.This paper studied the character of Gabor filter,the methods of feature extractor,principal component analysis,the theory of SVM and its parameters.The method proposed overcame dimension disaster and overfitting.The experiment with MNIST database validated there were ideal results with our method,and also the multi-class SVM was efficient.At last,we analyzed and compared the methods with traditional multi-class classification. |
