Dataset of Tomato Leaves

This database is divided into two datasets for tomato leaf images according to different image sources. The tomato leaf images of the first dataset are selected from the PlantVillage database with ten categories (nine disease categories and one health). Each image is composed of a single leaf and a single background, for a total of 14,531 images. After combining the original tomato leaf images and deleting unnecessary categories, we then adjusted the image size from 256 * 256 to 227 * 227. Afterwards, this database is divided into five subsets of 5-fold cross-validation. The detailed categories of the first dataset are: (1) Bacterial spot, (2) Early blight, (3) Healthy, (4) Late blight, (5) Leaf Mold, (6) Septoria leaf spot, (7) Target Spot, (8) Tomato mosaic virus, (9) Tomato yellow leaf curl virus, (10) Two-spotted spider mite The second dataset is images of Taiwan tomato leaves, with six categories (five disease categories and one health). It consists of a single leaf, multiple leaves, a single background and a complex background. We have 622 original images. The size of the picture is different, and we unified the image size to 227 * 227. Then we use data augmentation method to increase the number of pictures, including clockwise rotation with 90 degrees, 180 degrees, and 270 degrees; horizontal mirroring, vertical mirroring, reducing image brightness and increasing image brightness, etc. There are 4,976 images after data enhancement. The detailed categories of the second dataset are: (1) Bacterial spot, (2) Black leaf mold, (3) Gray leaf spot, (4) Healthy, (5) Late blight, (6) Powdery mildew

本数据库依据图像来源差异，划分为两个番茄叶片图像数据集。
第一数据集的番茄叶片图像采自PlantVillage数据库，共包含10个类别（9种病害类别与1种健康类别）。每张图像仅包含单张叶片与单一背景，总计14531张图像。在整合原始番茄叶片图像并剔除冗余类别后，我们将图像分辨率从256×256调整为227×227。随后，该数据库被划分为用于5折交叉验证的5个子集。第一数据集的详细类别如下：(1) 细菌性斑点病(Bacterial spot)，(2) 早疫病(Early blight)，(3) 健康叶片(Healthy)，(4) 晚疫病(Late blight)，(5) 叶霉病(Leaf Mold)，(6) 斑枯病(Septoria leaf spot)，(7) 靶斑病(Target Spot)，(8) 番茄花叶病毒病(Tomato mosaic virus)，(9) 番茄黄化曲叶病毒病(Tomato yellow leaf curl virus)，(10) 二斑叶螨危害(Two-spotted spider mite)。
第二数据集为台湾地区番茄叶片图像，共包含6个类别（5种病害类别与1种健康类别）。该数据集涵盖单张叶片、多张叶片、单一背景与复杂背景四种场景，原始图像共计622张，原始图像尺寸各异，我们将其统一调整为227×227。随后我们通过数据增强方法扩充图像数量，具体增强方式包括：90°、180°、270°顺时针旋转，水平镜像、垂直镜像，图像亮度调整（亮度降低与提升）等操作。经数据增强后，总图像量达4976张。第二数据集的详细类别如下：(1) 细菌性斑点病，(2) 黑叶霉病(Black leaf mold)，(3) 灰叶斑病(Gray leaf spot)，(4) 健康叶片，(5) 晚疫病，(6) 白粉病(Powdery mildew)。
