# RetinaGAN

|
15 |
+
Code Repository for: [**High-Fidelity Diabetic Retina Fundus Image Synthesis from Freestyle Lesion Maps**](https://opg.optica.org/abstract.cfm?uri=boe-14-2-533)
|
16 |
+
|

+
## About
|
18 |
+
|
19 |
+
RetinaGAN a two-step process for generating photo-realistic retinal Fundus images based on artificially generated or free-hand drawn semantic lesion maps.
|
20 |
+
|
21 |
+

|
22 |
+
|
23 |
+
StyleGAN is modified to be conditional in to synthesize pathological lesion maps based on a specified DR grade (i.e., grades 0 to 4). The DR Grades are defined by the International Clinical Diabetic Retinopathy (ICDR) disease severity scale; no apparent retinopathy, {mild, moderate, severe} Non-Proliferative Diabetic Retinopathy (NPDR), and Proliferative Diabetic Retinopathy (PDR). The output of the network is a binary image with seven channels instead of class colors to avoid ambiguity.
|
24 |
+
|
25 |
+

|
26 |
+
|
27 |
+
The generated label maps are then passed through SPADE, an image-to-image translation network, to turn them into photo-realistic retina fundus images. The input to the network are one-hot encoded labels.

+
## Usage
|
32 |
+
|
33 |
+
Download model checkpoints (see [here](checkpoints/README.md) for details) and run the model via Streamlit. Start the app via `streamlit run web_demo.py`.

+
## Example Images
|
36 |
+
|
37 |
+
Example retina Fundus images synthesised from Conditional StyleGAN generated lesion maps. Top row: synthetically generated lesion maps based on DR grade by Conditional StyleGAN. Other rows: synthetic Fundus images generated by SPADE. Images are generated sequentially with random seed and are **not** cherry picked.
