PMC-PhaseNet: ODConv-EMA enhanced YOLOv11n with focal loss for fine-grained phenological staging of Pinus tabuliformis male pine cones

Accurate, automated identification of phenological stages in Pinus tabuliformis male pine cones is critical for intelligent harvesting systems, yet fine-grained classification in natural field conditions remains challenging due to small target sizes, scale variation, background occlusion, and high m...
