Improving YOLOv11 for marine water quality monitoring and pollution source identification
AI summary Read the abstract
Researchers improved the YOLOv11 computer vision model to better detect and identify marine pollution sources, including oil spills, debris, and turbid water, in complex underwater environments. The enhanced model achieved higher detection accuracy and faster processing speeds compared to the standard version. The study demonstrates that advanced AI-based monitoring tools can meaningfully improve our ability to track and respond to marine pollution in real time.
Marine pollution has become an increasingly severe environmental issue, with oil spills, marine debris, and turbid water significantly impacting ecosystems and human health. The You Only Look Once (YOLO) series of target detection has been widely applied in Marine pollution monitoring. However, in complex underwater environments, challenges such as irregular pollutant shapes, varying scales, and background interference limit detection accuracy and robustness. To address these issues, this study proposes an improved YOLOv11 model that integrates Deformable Convolutional Networks version 4 (DCNv4) to enhance adaptability to deformable pollutants, improving detection precision. The Marine Fusion Loss (MFL) mechanism optimizes detection weight allocation among different pollutant categories, reducing false positives. Additionally, Multi-scale Feature Fusion (MFF) combines Convolutional Neural Networks (CNN) and Transformer-based feature extraction to enhance robustness in complex environments. Furthermore, instance segmentation is incorporated to refine boundary detection of pollutants. Experiments show that the improved YOLOv11 model outperforms the most advanced methods such as YOLOv8 and YOLOv10, with an average accuracy of 90.2% when 50% intersection exceeds union (mAP50) and an inference speed of 3.5ms, ensuring high precision and high efficiency. The results validate the effectiveness of the proposed method in enhancing marine pollution detection, providing a high-performance solution for intelligent environmental monitoring.

Detecting Microplastics in Aquatic Bodies Using Object Detection Model
AI summary Read the abstract
Microplastics—tiny plastic particles that pollute water and can work their way up the food chain into the fish and seafood we eat—are hard to track using traditional methods. This research shows that AI-powered image recognition tools (specifically YOLO models, a type of "smart camera" software) can automatically spot and count microplastics in water much faster than manual methods, with a newer version performing better than its predecessor. Faster, more accurate detection means scientists and regulators could monitor plastic pollution more effectively, which is an important step toward understanding and reducing our exposure to these contaminants.
