Classifiers fusion method to recognize handwritten persian numerals
This work addresses the challenge of handwritten Persian numeral recognition for applications in pattern analysis, but it is incremental as it combines existing classifiers with a known fusion approach.
The paper tackled the problem of recognizing handwritten Persian numerals by proposing a classifier fusion method using KNN, linear classifier, and SVM, achieving a correct recognition ratio of approximately 99.90% on a test set of 5,000 samples and 99.97% accuracy with cross-validation on a database of 20,000 samples.
Recognition of Persian handwritten characters has been considered as a significant field of research for the last few years under pattern analysing technique. In this paper, a new approach for robust handwritten Persian numerals recognition using strong feature set and a classifier fusion method is scrutinized to increase the recognition percentage. For implementing the classifier fusion technique, we have considered k nearest neighbour (KNN), linear classifier (LC) and support vector machine (SVM) classifiers. The innovation of this tactic is to attain better precision with few features using classifier fusion method. For evaluation of the proposed method we considered a Persian numerals database with 20,000 handwritten samples. Spending 15,000 samples for training stage, we verified our technique on other 5,000 samples, and the correct recognition ratio achieved approximately 99.90%. Additional, we got 99.97% exactness using four-fold cross validation procedure on 20,000 databases.
