摘要:

葡萄是全球范围内经济和文化上最具重要性的水果之一,欧洲和亚洲的表葡萄和葡萄酒产量相当可观。葡萄疾病如细菌性霜霉病、 downy mildew 和粉状霉病显著影响葡萄的生产和质量。因此,可持续的葡萄园管理需要早期和精确的疾病识别。当前的自动化方法,特别是基于YOLO框架的方法,往往计算成本高且缺乏可解释性,使其不适合实际应用场景。本研究提出使用优化的DenseNet 121进行葡萄叶疾病分类。领域特定的预处理和广泛的连接揭示了与疾病相关的特征,包括叶脉、边缘和病变。与基线CNN模型(包括ResNet18、VGG16、AlexNet和SqueezeNet)的广泛比较表明,所提出的模型具有优越的性能。它实现了99.27%的准确率,99.28%的F1分数,99.71%的特异度和98.86%的Kappa值,推理时间仅为9秒。交叉验证结果表明平均准确率为99.12%,表明其在所有类别上的强健性和泛化能力。我们还使用Grad-CAM突出显示与疾病相关的区域,以确保模型突出生理相关方面并增加透明度和信心。模型优化减少了实时部署的处理需求,而迁移学习确保了在较小且不平衡的数据集上的稳定性。有效的架构、领域特定的预处理和可解释的输出使所提出的框架在检测葡萄叶疾病方面具有可扩展性、精确性和计算成本低的特点。

英文摘要:

Grapes are among the most economically and culturally significant fruits on a global scale, and table grapes and wine are produced in significant quantities in Europe and Asia. The production and quality of grapes are significantly impacted by grape diseases such as Bacterial Rot, Downy Mildew, and Powdery Mildew. Consequently, the sustainable management of a vineyard necessitates the early and precise identification of these diseases. Current automated methods, particularly those that are based on the YOLO framework, are often computationally costly and lack interpretability that makes them unsuitable for real-world scenarios. This study proposes grape leaf disease classification using Optimized DenseNet 121. Domain-specific preprocessing and extensive connectivity reveal disease-relevant characteristics, including veins, edges, and lesions. An extensive comparison with baseline CNN models, including ResNet18, VGG16, AlexNet, and SqueezeNet, demonstrates that the proposed model exhibits superior performance. It achieves an accuracy of 99.27%, an F1 score of 99.28%, a specificity of 99.71%, and a Kappa of 98.86%, with an inference time of 9 seconds. The cross-validation findings show a mean accuracy of 99.12%, indicating strength and generalizability across all classes. We also employ Grad-CAM to highlight disease-related regions to guarantee the model is highlighting physiologically relevant aspects and increase transparency and confidence. Model optimization reduces processing requirements for real-time deployment, while transfer learning ensures consistency on smaller and unbalanced samples. An effective architecture, domain-specific preprocessing, and interpretable outputs make the proposed framework scalable, precise, and computationally inexpensive for detecting grape leaf diseases.
