Abstract

Handwritten Text Recognition (HTR) technology has brought about a revolution in the way handwritten data is converted and analyzed. This proposed work focuses on developing a Handwritten Text Recognition (HTR) system using deep learning through advanced deep learning architecture and techniques. The aim is to create a model for real-time analysis and detection of handwritten texts. The proposed deep learning architecture that is Convolutional Neural Networks (CNNs), is investigated and implemented with tools like OpenCV and TensorFlow. The model is trained on large handwritten datasets from EMNIST to enhance recognition accuracy. The system’s performance is evaluated based on accuracy, precision, real-time capabilities, and potential for deployment on platforms like Raspberry Pi. The actual outcome is a robust HTR system that can convert handwritten text to digital formats accurately. The developed system has achieved a high accuracy rate of 91.58% in recognizing English alphabets and digits, and outperformed other models with 81.77% mAP, 78.85% Precision, 79.32% Recall, 79.46% F1-Score, and 82.4% ROC. This research contributes to the advancement of HTR technology by enhancing its precision and utility.
