Carambola Disease Recognition Dataset

1. The scientific name of camranga is Averrhoa carambola Linn; the English name is Chinese gooseberry, or Carambola. It is a fruit tree belonging to the genus Averrhoa in the Oxalidaceae family. It is native to tropical Southeast Asia. 2. Camranga is a perennial green fruit of a small to medium-sized tree. The tree grows 15–25 feet tall with densely branched, spreading limbs and compound leaves that are 1-3 inches long. The fruit has a smooth, dark green skin. It is 3-6 inches in diameter and is angular in shape when mature. The fruit is green when unripe and turns yellow when ripe. Carambola can have a sour or tangy taste. Some trees bear fruit multiple times a year or consistently throughout the year. It is a good source of vitamins A and C. The fruit is typically available from September to January. 3. The whole fruit can be eaten, including the thin skin. Its organic acids help prevent cancer in the digestive system. Tannins in the juice of the leaves and unripe fruit assist in preventing the accumulation of blood clots. It is used as a primary detoxifier. The dried fruit is used for fever. Due to its cooling and tangy nature, it works as an effective remedy for heat-related issues, coughs, and as an anti-flatulent. Consuming camranga helps improve appetite and digestion. 4. Protecting camranga from pests is crucial for a successful fruit harvest. There are various pests that can attack camranga plants, and farmers need to take measures to safeguard their fruit crops. This may involve using pesticides, implementing integrated pest management techniques, or adopting organic farming methods to minimize the use of chemicals and ensure healthy crop yields. 5. Diseases in fruit crops are a widespread problem in agricultural production, and they have an adverse impact on the quality and productivity of the crops. Due to non-biological environmental factors, camranga diseases adversely affect the yield and quality of camranga, causing significant economic losses to farmers. The traditional identification of crop diseases is often time-consuming, labor-intensive, ineffective, and subjective. 6. In recent times, computer vision has shown great promise in conducting the classification and identification tasks of this kind. 7. A large dataset of nine different carambola classes—Healthy Fruit, Healthy Leaf, Stem Borer Disease, Anthracnose Disease, Leaf Insect Pest Disease, Early Blight Disease, Hooded Hopper Insect Disease, Bed Bugs Disease, and Fruit Borer Disease—is shown in order to create machine vision-based algorithms. 8. In reality, 559 images of carambola were initially collected from the field. Subsequently, to increase the quantity of data points, various image processing techniques were applied, such as shifting, flipping, zooming, shearing, brightness enhancement, and rotation, resulting in a total of 3913 augmented images derived from the original images.

1. 杨桃（camranga）的学名为阳桃（Averrhoa carambola Linn.）；英文名称为中国鹅莓（Chinese gooseberry）或杨桃（Carambola）。该物种隶属于酢浆草科（Oxalidaceae）阳桃属（Averrhoa），原产于热带东南亚地区。
2. 杨桃为中小型常绿多年生乔木所结的果实。该乔木株高可达15至25英尺，枝条茂密舒展，复叶长度为1至3英寸。果实表皮光滑，呈深绿色，直径3至6英寸，成熟时具棱角。未成熟时果实为绿色，成熟后转为黄色。杨桃口感酸甜，部分植株可一年多次结果或全年持续挂果。其富含维生素A与维生素C，果实通常于9月至次年1月上市。
3. 杨桃的全果均可食用，包括其薄果皮。果实中的有机酸有助于预防消化系统癌症；叶片与未成熟果实汁液中的单宁物质可帮助防止血栓形成。杨桃可用作主要的排毒剂，干燥果实可用于治疗发热。因其性凉且味酸，可有效缓解热证、咳嗽，还具有消胀理气的功效。食用杨桃有助于改善食欲与消化功能。
4. 对杨桃进行虫害防护对实现丰产至关重要。多种害虫可侵染杨桃植株，种植者需采取措施保护果实作物，例如施用农药、采用综合虫害管理技术，或采用有机种植方式以减少化学药剂使用量，保障作物健康增产。
5. 果树病害是农业生产中的普遍问题，会对作物的品质与产量产生不利影响。由非生物环境因素引发的杨桃病害，会降低杨桃的产量与品质，给种植者造成显著的经济损失。传统的作物病害鉴定方法通常耗时耗力、效果欠佳且主观性强。
6. 近年来，计算机视觉（computer vision）在这类分类与鉴定任务中展现出了巨大的应用潜力。
7. 为构建基于机器视觉（machine vision）的算法，本数据集涵盖9类杨桃相关样本：健康果实、健康叶片、茎蛀虫病、炭疽病、叶部虫害病、早疫病、盔沫蝉虫害病、臭虫病害以及果蛀虫病。
8. 最初，研究人员从田间采集了559张杨桃图像。随后，为扩充数据集规模，研究人员采用了平移、翻转、缩放、剪切、亮度增强以及旋转等多种图像处理技术对原始图像进行数据增强，最终得到共计3913张增强后的图像。
