## Overview

This dataset contains 747 Deep Fundus Images (DFIs) annotated for glaucomatous optic neuropathy (GON) and accompanied by quality scores.
The dataset is structured into an image folder and a labels file providing metadata and annotations.

## Dataset Structure

### 1. Images

- Located in the `Images/` folder.
- Contains 747 DFIs in JPG format with a 1:1 aspect ratio.
- Image naming convention: `x_y.jpg`
  - `x`: Patient ID (starting from 1)
  - `y`: Image number per patient (starting from 0)
  - Example: `188_1.jpg` → Second image of patient 188.

### 2. Labels File (`Labels.csv`)

A CSV file containing metadata and annotations for each image. It includes the following columns:

| Column Name   | Description                                                                |
| ------------- | -------------------------------------------------------------------------- |
| Image Name    | Filename of the DFI (e.g., `188_1.jpg`).                                   |
| Patient       | Unique patient ID.                                                         |
| Label         | Binary classification: `GON+` (glaucomatous) or `GON-` (non-glaucomatous). |
| Quality Score | Score ranging from 1 to 10.              				     |

## Dataset Statistics

- Total Images: 747
- Glaucomatous DFIs (GON+): 548
- Non-Glaucomatous DFIs (GON-): 199
