DDR-Augmented-Artifacts

Dataset Summary

DDR-Augmented-Artifacts provides fundus images augmented with realistic synthetic artifacts.
Artifacts were cropped from anonymized retina images showing reflections from blood vessels, segmented, and overlaid on DDR images using Gaussian feathered masks and Poisson blending.

Code Repository

The dataset is accompanied by code for artifact generation, preprocessing, and training, available at:

👉 GitHub Repository

This repository contains:

• Scripts for generating synthetic artifacts
• Example U-Net model for artifact removal

Supported Tasks

• Image Classification: Train and evaluate DR classifiers on artifact-rich data.
• Image Segmentation: Evaluate lesion/DR segmentation robustness under artifacts.
• Preprocessing / Artifact Removal: Train models to identify and remove imaging artifacts prior to downstream analysis.

---

Languages

• Image-based dataset (no natural language component).

Dataset Structure

Data Fields

• image_id: filename of the image (string)
• severity_level: integer label (0–4) indicating DR severity
  • 0 = No DR
  • 1 = Mild
  • 2 = Moderate
  • 3 = Severe
  • 4 = Proliferative DR

Data Splits

The dataset is provided as a flat collection of images with a CSV label file.
Users should generate train/val/test splits at the patient level to prevent data leakage.

Intended Uses

• Research on artifact robustness in medical imaging AI.
• Developing augmentation pipelines for retinal image datasets.
• Training preprocessing modules to detect and remove acquisition artifacts.

---

Limitations

• Synthetic artifacts may not capture full variability of real-world imaging conditions.
• Not intended for clinical use.

---

Ethics and Privacy

• All patches were derived from fully anonymized personal retinal images.
• No patient-identifiable data is present.
• Dataset is for research purposes only.
