An optimized YOLOv11-based model for surface defect detection on valve stems in refrigeration equipment
The RDD-YOLO model based on the YOLOv11n architecture is presented, which replaces specific convolutions in the backbone and neck with receptive field channel attention convolutions (RFCAConv) to enhance local target perception, and constructs a depth-adaptive kernel spatial pyramid pooling factorization (DAK_SPPF) mod...
