Abstract

Since author’s writing styles are often ambiguous, writer recognition is an appealing research problem for handwritten manuscript investigation. Pattern identification allows for recognizing the author of a handwritten work. Due to the variety of text visuals, especially handwriting images, author recognition is challenging. Convolution Neural Network (CNN) excels in many fields. This paper presents a complete framework that emphasizes feature engineering and uses a simple, efficient deep neural network. Writer recognition begins with data collection. Programming a technique to generate several database texts enhances the data. To capture and categorize feature information, a multi-path CNN with a Bidirectional Long Short Term Memory (Bi-LSTM) module is developed. By integrating CNN and Bi-LSTMs, the proposed model combines spatial and temporal information, offering a comprehensive representation of handwriting. This synergy makes it particularly effective in handling the variability and complexity of offline writer recognition. Languages are occasionally blended when writing in multilingual regions. The system performed well on two publicly accessible handwritten English language benchmark databases, CVL and IAM, in addition to an in-house bilingual database comprising English and Hindi scripts. This study is unconventional since it addressed offline writer recognition using monolingual and bilingual handwritten text corpora. Analytically, our findings are encouraging compared to previous studies. The model achieves accuracies of 98.78% on the IAM dataset, 98.55% on the CVL dataset, and 99% on an in-house bilingual dataset. These results demonstrate a significant improvement over other state-of-the-art methodologies in offline writer recognition.
