Abstract

The initial stage of recognizing individual characters is through the use of machine in analyzing handwritten documents. This research focuses on the recognition of isolated characters obtained from handwritten English documents. The focus is given to the study of preprocessing and feature extraction methods. To bring about size uniformity, the character image samples are normalized to 70X50 pixel sizes using nearest neighbor interpolation method. A normalized image is next transformed into a binary image utilizing Otsu’s threshold selection technique. This is followed by thinning or contour tracing. An important concern in character recognition is the selection of best discriminative features. This study took an overview of various statistical and structural features and recommended a unique and new view on the basis of features. The effectiveness of these features on handwritten English character recognition is experimented using MultiLayer Perceptron (MLP) and Support Vector Machine (SVM) classifiers. The proposed modified view based feature is found to be very efficient. An extensive assessment experiments outcomes carried out with different features/combination of features and classifiers is presented. From the experiments, view based features are found to give high recognition accuracy. By combining different features in an optimal way, recognition accuracy of 97% is obtained.
