An Intelligent Paper Currency Recognition System for Blind and Visually Impaired Persons in Bangladesh.

Abstract: Low vision and blindness have become a global public health concern due to the rapid growing population, especially in low income nations. They frequently use banknotes for daily purchases and bill payment. The similarity of paper surface and size across different denominations makes recognizing currency one of the other major challenges faced by them. Furthermore, the sizes and colors of banknotes are causing major problems for blind or visually impaired people. Thus, a real-time paper currency recognition system is necessary for visually challenged people to avoid depending on others for financial transactions. This project aims to introduce a deep learning-based assistance framework, named Vision-Assist, for detecting and recognizing Bangladeshi paper currency in real-time, specifically for individuals who are blind or visually impaired. To achieve this, the YOLOv5 model was employed to detect currency regions. The YOLOv5 model achieves an impressive mean average precision score of 0.95, indicating its superior performance in accurately identifying currency areas compared to other potential detection models. The experiment was conducted on the NSTU-BDTAKA dataset, which includes 28875 diverse images of Bangladeshi paper currency. Achieving a testing accuracy of 94.94%, the proposed Vision-Assist approach demonstrated excellent performance. Results show that Vision-Assist outperforms other current methods and provides greater applicability in the unrestricted setting of currency recognition tasks. The model demonstrates strong potential for enhancing financial independence among visually impaired individuals.

Predicting Student Engagement in Collaborative Learning using Computer Vision: In the Perspective of Bangladesh.

Abstract: Monitoring student engagement in real time is increasingly vital in educational research, especially as intelligent classroom technologies proliferate. While previous research focused on single components such as gaze tracking or emotion recognition, a few studies offer unified approaches to holistic involvement assessment. The lack of comprehensive, contextually appropriate datasets is the main cause of this. This paper presents a multimodal deep learning framework that integrates face detection, gaze estimation, and facial expression recognition to comprehensively detect and classify student engagement levels. To accomplish this, a novel multimodal dataset has been created: a gaze detection dataset with 8191 original images augmented to 24573 samples, and a facial expression recognition dataset with 9008 original images expanded to 27023 samples. Both datasets were collected in actual classroom settings to ensure ecological validity. The proposed framework, which uses YOLOv8 for face detection and LightGBM for expression and gaze classification, is designed for interpretability and real-time responsiveness. Unlike previous approaches prone to overfitting or unsuited for dynamic settings, the framework demonstrates strong generalization, as evidenced by minimal divergence between training and validation curves. It achieves classification accuracies of 96\% and 97\% for expression and gaze recognition, respectively, and an F1-score of 0.99 for face detection. These results underscore the value of purpose-built datasets in enabling nuanced, robust detection of engagement states such as attentiveness, boredom, or distraction.
