The Critical Need for AI in Water Safety
Drowning remains a significant global public health issue, contributing to an estimated 236,000 fatalities annually. Traditional surveillance methods, heavily reliant on human observation, are prone to delays, fatigue, and misinterpretation, severely impacting rescue times and survival rates. The advancement of Artificial Intelligence, particularly deep learning, offers a revolutionary approach to mitigate these tragic incidents.
AI-driven systems can provide constant, unbiased monitoring, significantly enhancing the chances of timely intervention. This research explores how cutting-edge AI, specifically Convolutional Neural Networks and Vision Transformers, can transform underwater drowning detection into a highly reliable and efficient solution for public safety.
Robust Data and Advanced Architectures
The study’s methodology involved data collection at Walailak University’s swimming pool using a high-quality underwater camera. A custom dataset was created from four volunteers simulating various swimming and drowning actions, ensuring a diverse and representative data source. Data augmentation techniques (rotations, zooms, flips) were applied to enhance dataset diversity, addressing the challenges of limited labeled data and improving model generalization under varying underwater conditions.
Five CNN architectures—MobileNetV3, EfficientNet, ResNet, AlexNet, and DenseNet121—alongside Vision Transformers (ViTs) were evaluated. These models were fine-tuned using ImageNet weights and trained for binary classification (drowning vs. non-drowning) with performance measured by accuracy, precision, recall, F1-score, and inference speed.
Superior Accuracy and Real-time Efficiency
The evaluation revealed that EfficientNet achieved the highest detection accuracy of 97% for swimming and 98% for drowning, with a real-time inference speed of 0.04 seconds. While ViTs demonstrated strong feature extraction capabilities and high accuracy (up to 99%), they required more computational resources and had a longer inference time of 0.12 seconds.
MobileNetV3 stood out for its computational efficiency, achieving inference times as low as 0.02 seconds, making it highly suitable for real-time applications despite slightly lower accuracy (95-97%). The use of transfer learning significantly enhanced model generalization, reducing false alarms and improving response efficiency.
Grad-CAM visualizations confirmed that models, especially EfficientNet, focused consistently on critical distress indicators in the upper body, arms, and face for drowning cases, and smoother movements for normal swimming. This validates the models' ability to accurately differentiate behaviors.
Addressing Limitations and Charting the Future
Despite promising results, the study identified limitations, including a relatively small dataset and insufficient environmental variability. Future work will focus on optimizing Vision Transformers (ViTs) for real-time deployment and integrating them with IoT-based alert systems to enhance responsiveness and effectiveness.
Further enhancements could include exploring multimodal approaches, such as motion tracking and thermal imaging, to improve detection accuracy and robustness in diverse underwater environments. These efforts aim to provide an even more reliable and comprehensive solution for automated underwater drowning detection, ultimately bolstering water safety.
