Growing shiitake at home or at scale means sorting by hand every time; AI trained on datasets like this one could soon tell a ready-to-harvest cap from an underripe one faster and more consistently than any human eye.
Sorting and grading shiitake mushrooms is still done by hand, which is slow and inconsistent. A research team photographed thousands of shiitake mushrooms as they actually grow, under real lighting and crowded conditions, and carefully labeled each one by variety, growth stage, and shape. The result is a free dataset that developers can use to train computers to recognize and grade mushrooms automatically.
Key Findings
The dataset includes 1,782 original high-resolution images expanded to 6,500 via augmentation, with 43,752 individually annotated mushroom instances.
Three commercially important varieties (9608, Chunsheng No. 1, Qihe No. 9) are represented across three growth stages plus a deformed-mushroom category.
Images capture realistic challenges including complex lighting, occlusion, dense clustering, and multiple viewing angles, making the dataset applicable to real-world AI deployment.
chevron_right Technical Summary
Researchers built a large, freely available image dataset of shiitake mushrooms photographed in real growing conditions, covering three varieties and four categories including growth stages and deformed specimens. The dataset is designed to train AI systems that can automate mushroom grading, harvesting robots, and yield estimation.
