Lightweight Architecture with GhostConv
The model incorporates Ghost Convolution (GhostConv) layers, replacing traditional convolutions in the backbone. This substantially reduces the number of parameters and computational resources, making the model suitable for deployment on resource-constrained terminal devices while maintaining high accuracy.
Multi-Dimensional-Fusion Neck (MDF-Neck)
The traditional Feature Pyramid Network (FPN) is replaced with a novel Multi-Dimensional-Fusion neck (MDF-Neck). This design enhances small-object perception and reduces model parameters through dense cross-scale connectivity and adaptive weighting across feature layers (P1-P4), improving robustness to varying defect sizes and complex backgrounds.
Enhanced Feature Fusion with Virtual Fusion Head & Attention Concat
To achieve multi-dimensional integration in the neck, a Virtual Fusion Head is utilized for adaptive enhancement of small-defect regions through resolution-aware pooling and alignment. Additionally, an Attention Concat module guides feature aggregation via lightweight spatial-channel attention, significantly improving overall detection performance, especially for low-contrast, small-scale defects. This dual mechanism ensures robust feature extraction while preserving diverse layer information and amplifying the influence of key features on prediction results.
PSF-YOLO Enterprise Workflow
The proposed PSF-YOLO model integrates several key components to achieve efficient and accurate steel surface defect detection. The process involves initial data augmentation, lightweight feature extraction, multi-dimensional feature fusion, and final detection for industrial deployment.
Performance Benchmarking on GC10-DET+ and Generalization
PSF-YOLO demonstrates superior performance compared to various YOLO variants and other lightweight models on the GC10-DET+ dataset, achieving higher mAP50 and mAP50-95 with significantly fewer parameters. It also shows robust generalization on external datasets like RSOD and annotated wind turbine surface damage.

The synergy between the Virtual Fusion Head and Attention Concat module is crucial for PSF-YOLO's superior performance on small and low-contrast defects. The Virtual Fusion Head efficiently merges information from P1, P2, P3, and P4 layers, preserving diverse layer information and amplifying key features. The Attention Concat, through its triple-attention mechanism, directly operates on original data without dimensionality reduction, maintaining richer contextual information and enhancing propagation. This combination ensures enhanced small object detection while balancing parameter efficiency and detection accuracy.
