Abstract :
Offline handwritten character recognition has gained significant attention in the fields of artificial intelligence and
pattern recognition because of its applications in intelligent document analysis, banking automation, postal systems,
educational platforms, and biometric authentication. The recognition of handwritten characters remains a challenging task
due to variations in writing styles, stroke orientation, character deformation, background noise, and image distortion.
Traditional Artificial Neural Network (ANN)-based approaches often depend on handcrafted feature extraction methods
and exhibit limited robustness when applied to large and diverse handwritten datasets. To address these limitations, this
paper proposes an Attention-Enhanced Convolutional Neural Network (AE-CNN) framework for offline handwritten
character recognition. The proposed system integrates adaptive image preprocessing, data augmentation, convolutional
feature extraction, and attention-guided learning to improve classification accuracy and feature discrimination. Initially, a
baseline ANN model is implemented to evaluate the limitations of conventional neural architectures. Subsequently, a deep
CNN model integrated with an attention mechanism is developed to improve recognition capability for visually similar
handwritten characters. Experimental evaluation is performed using the EMNIST handwritten dataset. The obtained results
demonstrate that the proposed AE-CNN framework achieves improved classification performance, enhanced generalization
capability, and better robustness against noisy handwritten samples compared to traditional ANN and conventional CNN
models. The proposed approach provides an efficient and scalable solution for intelligent handwritten recognition systems
used in real-world document processing applications.
