Abstract: This paper proposes an improved lightweight YOLOv5-based method for detecting maize leaf disease detection by introducing the GhostNet module to replace the backbone network and optimizing the neck network with the GSConv module, significantly reducing model parameters and computational complexity. Experimental results demonstrate that the enhanced YOLOv5s-Ghost-GSConv-seg maintains high detection accuracy while achieving a 37.5% reduction in parameters, a 20.8% decrease in computational cost, and a 15.6% improvement in inference speed. The multi-scale feature fusion design effectively balances detection accuracy and real-time performance, providing an efficient solution for lightweight object detection in smart agriculture applications.
