Deep Learning Models
This category focuses on the advanced deep learning architectures utilized in the study, specifically YOLOv8, YOLOv9, and YOLOv10. It delves into their unique enhancements, such as context aggregation in YOLOv8, GELAN (Generalized Efficient Layer Aggregation Network) and PGI (Programmable Gradient Information) in YOLOv9, and NMS-free training in YOLOv10. The discussion highlights how these innovations contribute to improved accuracy, computational efficiency, and robustness in detecting Egyptian banknotes under diverse real-world conditions. It also contrasts these models with traditional approaches and lightweight alternatives like EfficientNet-Lite and ShuffleNet.
Dataset and Preprocessing
This section details the dataset collection and preprocessing methodology. The dataset comprises 2,000 annotated images of Egyptian banknotes, obtained from a Kaggle AI competition. Emphasis is placed on the balanced representation of six denominations (5, 10, 20, 50, 100, 200 EGP) and the inclusion of diverse real-world conditions (varying lighting, occlusions, rotations, backgrounds). The preprocessing steps, including resizing images to 640x640 and converting XML annotations to YOLO's text format, are explained to ensure compatibility and optimal training for the deep learning models.
Performance Evaluation
This category covers the comprehensive evaluation of the models using a 5-fold cross-validation approach. Key performance metrics—Precision, Recall, F1 Score, mAP@0.5, and mAP@0.5:0.95—are discussed, with a particular focus on how YOLOv10 consistently outperforms YOLOv8 and YOLOv9. The section also includes a statistical validation using ANOVA and post-hoc Tukey's HSD tests to confirm the significance of performance differences. Furthermore, baseline comparisons with ResNet-50 and SqueezeNet are provided to contextualize the advanced models' capabilities in object detection versus classification tasks.
Real-time Usability & Accessibility
This section examines the practical implications of the system for visually impaired users, focusing on real-time usability and accessibility. It highlights the inference speed (FPS) of each YOLO model, with YOLOv10 maintaining an acceptable 34 FPS while achieving superior accuracy. The discussion underscores how the system promotes financial independence and inclusion by providing a reliable and scalable AI-powered solution for regional currency recognition, addressing the limitations of prior systems and contributing to assistive technology advancements.
