The DDR (Diabetic Retinopathy Detection) dataset is a large-scale collection of retinal fundus images designed for training and evaluating algorithms in diabetic retinopathy (DR) grading and lesion-level segmentation. It provides both image-level DR labels and pixel-level annotations of pathological features, making it suitable for classification and segmentation tasks.

Dataset Structure

🧩 Categories

The dataset includes five DR severity levels, labeled according to the International Clinical Diabetic Retinopathy (ICDR) scale:

Label	Description
0	No Diabetic Retinopathy
1	Mild Nonproliferative DR
2	Moderate Nonproliferative DR
3	Severe Nonproliferative DR
4	Proliferative DR

Additionally, lesion masks are provided for:

—Microaneurysms
—Hemorrhages
—Hard exudates
—Soft exudates

Data Summary

Split	# Images	Annotation Type	Image Resolution
Train	~9,000	Image-level + lesion masks	3216×2136 px (avg.)
Test	~1,000	Image-level + lesion masks	3216×2136 px (avg.)

Total: ~10,000 color fundus images collected from multiple clinical sites in China.
