Enhanced YOLO-based framework for accurate detection and identification of common wheat impurities with distinct objects
Unlocking Enterprise Efficiency with AI: A Deep Dive
This study introduces an advanced YOLO-based framework to precisely detect and identify various impurities in wheat grains. By comparing YOLOv5 and YOLOv8 models across different image resolutions, the research highlights an optimal balance between accuracy and speed for both laboratory and real-time applications. The framework demonstrates high precision for distinct impurities and robust performance in real-world conditions, providing a non-destructive method crucial for enhancing wheat quality assessment.
Key Takeaway: The YOLOv5n model, particularly at a 320x320 resolution, offers superior detection speed with maintained accuracy, making it ideal for real-time wheat impurity detection in agricultural settings. While larger models (YOLOv5x, YOLOv8x) provide slightly higher accuracy, the speed trade-off is significant, reinforcing YOLOv5n's suitability for time-critical applications.

Core AI Concepts & Their Application
YOLO Model Selection
The research evaluated YOLOv5n, YOLOv5x, YOLOv8n, and YOLOv8x models. YOLOv5n at 320x320 resolution emerged as optimal for real-time applications due to its balance of speed and accuracy (7.1ms inference, 0.954 mAP). Larger models showed marginal accuracy gains but significantly slower processing.
Impurity Detection Accuracy
High mAP@50 values (over 95%) were achieved for distinct impurities like stones, chaff, and weeds. Impurities with similar visual characteristics, such as shriveled grains and sun pest-damaged grains, presented a greater challenge, with mAP values around 85-88%.
Impact of Image Resolution
The study demonstrated that 320x320 resolution provided a good trade-off. While 640x640 offered slightly higher accuracy, the increase was minimal compared to the significant increase in inference time. 160x160 resolution led to a noticeable decline in performance.
