Vempati Lakshmi Sravani, Piyush Pratap Singh . Hybrid Approach for Recognition of Isolated Handwritten Fraction Notations in Telugu Script. International Journal of Computer Applications. 186, 19 ( May 2024), 38-45. DOI=10.5120/ijca2024923600
Recognition of handwritten digits in regional Indian languages presents formidable challenges due to the vast array of scripts and variability in writing styles. Despite notable advancements in research techniques and databases for recognizing "0 to 9" digits in Indian scripts such as Bangla, Kannada, Devanagari, Oriya, and Telugu, there exists a conspicuous gap in research explicitly addressing the recognition of "fraction" notations unique to the Telugu script. Consequently, the proposed methodology integrates deep learning techniques, employing Convolutional Neural Networks (CNNs) for feature extraction and Support Vector Machines (SVMs) with various kernels for classification. This approach is explicitly tailored towards recognizing handwritten Telugu "fraction" notations, aiming to fill the existing research void in this domain. To facilitate model training, a comprehensive dataset is curated comprising 4000 handwritten Telugu fraction images covering eight distinct notation classes and enhanced dataset diversity through data augmentation techniques. Extensive experimental validation showcases the efficacy of the proposed hybrid CNN-SVM framework, achieving an impressive accuracy of 99.86% using the RBF kernel, outperforming the standalone CNN model (99.67% accuracy). These findings highlight the effectiveness of the proposed method in this underexplored field of recognizing handwritten Telugu fractions that can contribute to the digital preservation of ancient Telugu manuscripts and fostering linguistic diversity, paving the way for broader language technology applications.
