Infrared ship target detection algorithm PEW_YOLOv8 in complex environments
This paper introduces PEW_YOLOv8, an advanced infrared ship target detection algorithm designed for complex maritime environments. It addresses challenges like fog, blurring, small target detection, and occlusion by integrating FFA-Net for image pre-processing, PGIG-Backbone for enhanced feature extraction, EMA-Neck for multi-scale attention, and WIoU Loss for improved bounding box regression. Experimental results demonstrate a significant improvement in detection accuracy over baseline YOLOv8 on a specialized infrared ship dataset.
Key Metrics & Projected Impact
PEW_YOLOv8 achieves a detection accuracy of 92.2% on the Raytron Technology infrared ship dataset, marking a 3.9% increase in mAP50 and 3.1% in mAP50:95 compared to the original YOLOv8. This enhancement translates directly into more reliable and precise maritime monitoring, enabling earlier threat detection and improved operational safety in challenging conditions.

Loss Function
This section details the integration of the FFA-Net module for addressing image quality issues such as fog, blurring, and distortion in infrared ship images. FFA-Net combines channel and pixel attention with local residual learning to restore crucial image detail, ensuring better input for subsequent detection stages.
This section explains the proposed PGIG-Backbone network, designed to overcome information bottleneck problems in diverse scenarios and target sizes. By utilizing efficient spatial encoding technology, it secures reliable gradient information for network weight updates, significantly improving detection for low-resolution infrared ship images.
The EMA-Neck (Efficient Multi-scale Attention) network is introduced here to enhance feature fusion and extraction. It assigns dynamic weights across feature maps, emphasizing critical features for small and weak targets, thereby boosting multi-scale object detection capabilities and model inference speed.
This part describes the adoption of the WIoU Loss (Wise-IoU v3) bounding box loss function. Its dynamic non-monotonic focusing mechanism evaluates anchor box quality based on 'outlier degree' rather than simple IoU, reducing harmful gradients from low-quality examples and improving performance for targets with unclear boundaries.
