SamruddhK/coffee-bean-grading-dataset

这是一个包含3877张高分辨率生咖啡豆图像的数据集，这些图像来自印度卡纳塔克邦的科格地区，一个主要的咖啡生产区。每个豆子被归类为四个质量等级之一：优质（A级）、良好（B级）、标准（C级）和次品（D级）。共有2284个豆子使用LabelMe JSON格式进行了多边形掩码和等级标签的注释，支持分类、实例分割、自动分级和缺陷检测等研究。该数据集可用于多类实例分割训练、自动分级和排序系统、农业缺陷检测研究、食品质量保证研究和鲁棒的低成本供应链检测系统。

This dataset consists of 3877 high-resolution images of raw coffee beans, collected from the Coorg region in Karnataka, India, a major coffee-producing area. Each bean is categorized into one of four quality grades: Premium (Grade A), Good (Grade B), Standard (Grade C), and Defective (Grade D). A total of 2284 beans are annotated with polygon masks and grade labels in LabelMe JSON format, supporting research in classification, instance segmentation, automated grading, and defect detection. The dataset can be used for multi-class instance segmentation training, automated grading and sorting systems, agricultural defect detection research, food quality assurance studies, and robust low-cost supply chain inspection systems.
