Abstract

In India, Telugu is one of the official languages and it is a native language in the Andhra Pradesh and Telangana states. Although research on Telugu optical character recognition (OCR) began in the early 1970s, it is still necessary to develop effective printed character recognition for the Telugu language. OCR is a technique that aids machines in identifying text. The main intention in the classifier design of the OCR systems is supervised learning where the training process takes place on the labeled dataset with numerous characters. The existing OCR makes use of patterns and correlations to differentiate words from other components. The development of deep learning (DL) techniques is useful for effective printed character recognition. In this context, this paper introduces a novel DL based residual network model for printed Telugu character recognition (DLRN-TCR). The presented model involves four processes such as preprocessing, feature extraction, classification, and parameter tuning. Primarily, the images of various sizes are normalized to 64x64 by the use of the bilinear interpolation technique and scaled to the 0, 1 range. Next, residual network-152 (ResNet 152) model-based feature extraction and then Gaussian native Bayes (GNB) based classification process is performed. The performance of the proposed model has been validated against a benchmark Telugu dataset. The experimental outcome stated the superiority of the proposed model over the state of art methods with a superior accuracy of 98.12%.
