To address the issues of low detection accuracy, missed detections, and false positives in the YOLO model, this study proposes an improved YOLOv8n-based detection and counting model for green walnuts, ...

Experimental results show that, compared to the YOLOv8n model, the proposed model achieves a 15.3% reduction in parameters, a 9.4% increase in precision, a 6% improvement in recall, and gains of 8.1% ...

The YOLOv8n-DDSW object detection algorithm has been improved as follows: (1) deformable convolution is introduced into the backbone C2f structure; (2) the DPSE channel attention mechanism is ...
