To address mango leaf disease recognition in complex in-field scenes, where background interference and simultaneous infections across multiple leaves lead to feature recognition difficulties and multi-task segmentation problems, this paper proposes G-Mask2Former, a structure-space-guided model that achieves collaborative segmentation of leaf instances and lesion semantics. The method jointly learns leaf and lesion segmentation within a shared feature space, and leverages a leaf-structure prior to impose spatial constraints on the lesion predictions. First, based on Mask2Former, we use multi-scale pixel representations and mask attention to extract effective features of mango leaf diseases in complex scenes; by constructing pseudo-instances of lesions, we achieve leaf instance segmentation and lesion semantic segmentation within a single model, thereby simplifying model deployment and inference. Second, through a leaf structure-space soft gating module, the model is guided to focus on leaf regions, reducing interference from complex environments. Finally, we conduct experiments on a mango leaf disease dataset collected in complex in-field scenes and perform comparative analyses against other models. The proposed method achieves superior overall performance over classical baselines for segmenting mango leaves and diseases in complex in-field scenes. On the test set, the average precision (AP) for leaf instance segmentation reaches 87.37%, while the mean Intersection-over-Union (mIoU) for lesion semantic segmentation reaches 82.83%. The proposed method would provide an effective solution for mango leaf disease segmentation in complex environments and facilitates quantitative disease assessment.

针对田间复杂场景下芒果叶片病害识别中,复杂背景干扰与多叶片同时出现病症导致的特征识别困难和多任务分割问题,本研究提出了结构空间引导的G-Mask2Former模型,实现对叶片实例与病斑语义的协同分割。该模型在共享特征空间内同时学习叶片和病斑分割,并辅助叶片结构先验对病斑进行空间约束。首先,基于Mask2Former的多尺度像素表征与掩码注意力提取复杂场景中芒果叶片病害有效特征,结合构建病斑伪实例,在单一模型中实现叶片实例和病斑语义分割,简化模型部署和推理流程;然后,通过叶片结构空间软门控模块,引导模型关注叶片区域,以减少复杂环境干扰;最后在复杂场景下芒果叶片病害数据集上进行试验,并与其他模型进行对比分析。结果表明:该模型对复杂场景芒果叶片与病害分割的综合表现优于其他传统模型。在测试集上,实例分割平均精度(AP)达到87.37%,语义分割平均交并比(mIoU)达到82.83%。该方法可为复杂环境中芒果叶片病害的诊断提供有效的量化解决方案。

针对田间复杂场景下芒果叶片病害识别中,复杂背景干扰与多叶片同时出现病症导致的特征识别困难和多任务分割问题,本研究提出了结构空间引导的G-Mask2Former模型,实现对叶片实例与病斑语义的协同分割。该模型在共享特征空间内同时学习叶片和病斑分割,并辅助叶片结构先验对病斑进行空间约束。首先,基于Mask2Former的多尺度像素表征与掩码注意力提取复杂场景中芒果叶片病害有效特征,结合构建病斑伪实例,在单一模型中实现叶片实例和病斑语义分割,简化模型部署和推理流程;然后,通过叶片结构空间软门控模块,引导模型关注叶片区域,以减少复杂环境干扰;最后在复杂场景下芒果叶片病害数据集上进行试验,并与其他模型进行对比分析。结果表明:该模型对复杂场景芒果叶片与病害分割的综合表现优于其他传统模型。在测试集上,实例分割平均精度(AP)达到87.37%,语义分割平均交并比(mIoU)达到82.83%。该方法可为复杂环境中芒果叶片病害的诊断提供有效的量化解决方案。

To address mango leaf disease recognition in complex in-field scenes, where background interference and simultaneous infections across multiple leaves lead to feature recognition difficulties and multi-task segmentation problems, this paper proposes G-Mask2Former, a structure-space-guided model that achieves collaborative segmentation of leaf instances and lesion semantics. The method jointly learns leaf and lesion segmentation within a shared feature space, and leverages a leaf-structure prior to impose spatial constraints on the lesion predictions. First, based on Mask2Former, we use multi-scale pixel representations and mask attention to extract effective features of mango leaf diseases in complex scenes; by constructing pseudo-instances of lesions, we achieve leaf instance segmentation and lesion semantic segmentation within a single model, thereby simplifying model deployment and inference. Second, through a leaf structure-space soft gating module, the model is guided to focus on leaf regions, reducing interference from complex environments. Finally, we conduct experiments on a mango leaf disease dataset collected in complex in-field scenes and perform comparative analyses against other models. The proposed method achieves superior overall performance over classical baselines for segmenting mango leaves and diseases in complex in-field scenes. On the test set, the average precision (AP) for leaf instance segmentation reaches 87.37%, while the mean Intersection-over-Union (mIoU) for lesion semantic segmentation reaches 82.83%. The proposed method would provide an effective solution for mango leaf disease segmentation in complex environments and facilitates quantitative disease assessment.
