摘要

水稻是全球重要的主食,其持久的可持续性取决于水稻叶片病害的及时发现。因此,有效地检测已经发生的疾病对于解决人工视觉识别和化学测试的成本至关重要。近年来,作物叶片病理的鉴定主要依赖于使用专门设备的人工方法,这被证明是耗时和低效的。本研究通过利用深度学习(DL)和迁移学习技术来准确识别和分类水稻叶片病害,提供了一种补救措施。与基准数据集一起组装了一个包含5932张自生成水稻叶片图像的综合数据集,并将其分为9类,而不考虑病害在叶片上传播的程度。这些类别包括不同的状态,包括健康叶片,轻度和重度枯萎病,轻度和重度结核,轻度和重度稻瘟病,轻度和重度褐斑病。在经过园艺专家验证的细致的人工标记和数据集分割之后,实施数据增强策略来扩大图像数量。使用提出的定制卷积神经网络模型对数据集进行评估。它们的性能与其他迁移学习方法(如VGG16、Xception、ResNet50、DenseNet121、Inception ResnetV2和Inception V3)一起仔细检查。提出的定制VGG16模型的有效性是通过其对未见图像的泛化能力来衡量的,产生了99.94%的卓越准确率,超过了现有最先进模型设定的基准。此外,分层特征提取也被可视化为可解释的AI。

DeepRice: A deep learning and deep feature based classification of Rice leaf disease subtypes

Rice stands as a crucial staple food globally, with its enduring sustainability hinging on the prompt detection of rice leaf diseases. Hence, efficiently detecting diseases when they have already occurred holds paramount importance for solving the cost of manual visual identification and chemical testing. In the recent past, the identification of leaf pathologies in crops predominantly relies on manual methods using specialized equipment, which proves to be time-consuming and inefficient. This study offers a remedy by harnessing Deep Learning (DL) and transfer learning techniques to accurately identify and classify rice leaf diseases. A comprehensive dataset comprising 5932 self-generated images of rice leaves was assembled along with the benchmark datasets, categorized into 9 classes irrespective of the extent of disease spread across the leaves. These classes encompass diverse states including healthy leaves, mild and severe blight, mild and severe tungro, mild and severe blast, as well as mild and severe brown spot. Following meticulous manual labelling and dataset segmentation, which was validated by horticulture experts, data augmentation strategies were implemented to amplify the number of images. The datasets were subjected to evaluation using the proposed tailored Convolutional Neural Networks models. Their performance are scrutinized in conjunction with alternative transfer learning approaches like VGG16, Xception, ResNet50, DenseNet121, Inception ResnetV2, and Inception V3. The effectiveness of the proposed custom VGG16 model was gauged by its capacity to generalize to unseen images, yielding an exceptional accuracy of 99.94%, surpassing the benchmarks set by existing state-of-the-art models. Further, the layer wise feature extraction is also visualized as the interpretable AI.
