Abstract： Maize, a crucial staple crop in China, is frequently beset by production challenges stemming from diseases such as maize Northern Leaf Blight, Southern Corn Leaf Blight, and rust, along with insect pests. These maladies significantly undermine maize yield and quality, presenting a potential menace to agricultural production stability. In recent times, visual disease detection techniques have emerged as pivotal instruments for disease management, offering heightened precision relative to conventional methods. This paper leverages the Mask R-CNN architecture as its foundation, integrating DyHead, Groie, and OHEM modules to augment the model's proficiency in segmenting images containing minute disease manifestations. The enhanced Mask R-CNN model exhibits outstanding performance in disease image segmentation, witnessing a 4% uplift in mean average precision (mAP) and an 8.5% enhancement in accuracy for small object segmentation. Compared to analogous instance segmentation models like YOLOv5 and YOLACT++, this model displays superior prowess. To substantiate the utility of each incorporated module, ablation studies were carried out, revealing their constructive roles. Thus, this methodology furnishes a sturdy theoretical underpinning and technological means for the efficacious and precise detection of maize Northern Leaf Blight.
