<!-- Provide a quick summary of what the model is/does. --> |
|
|
|
This SegFormer model has undergone specialized fine-tuning on the [REFUGE challenge dataset](https://refuge.grand-challenge.org/), |
|
a public benchmark for semantic segmentation of anatomical structures in retinal fundus images. |
|
The fine-tuning enables expert-level segmentation of the optic disc and optic cup, two critical structures for ophthalmological diagnosis. |

## Uses |
|
|
|
<!-- Address questions around how the model is intended to be used, including the foreseeable users of the model and those affected by the model. --> |
|
|
|
This pretrained model enables semantic segmentation of key anatomical structures, namely, the optic disc and optic cup, in retinal fundus images. |
|
It takes fundus images as input and outputs the segmentation results. |
|
|
|
## Bias, Risks, and Limitations |
|
|
|
<!-- This section is meant to convey both technical and sociotechnical limitations. --> |
|
|
|
The model has undergone specialized training and fine-tuning exclusively using retinal fundus images, |
|
with the objective to perform semantic segmentation of anatomical structures including the optic disc and optic cup. |
|
Therefore, in order to derive optimal segmentation performance, it is imperative to ensure that only fundus images are entered as inputs to this model. |
|
|
|
## How to Get Started with the Model |
|
|
|
Use the code below to get started with the model. |
|
|
|
```python |
|
import cv2 |
|
import torch |
|
import numpy as np |
|
|
|
from transformers import AutoImageProcessor, SegformerForSemanticSegmentation |
|
|
|
image = cv2.imread('./example.jpg') |
|
image = cv2.cvtColor(image, cv2.COLOR_BGR2RGB) |
|
|
|
processor = AutoImageProcessor.from_pretrained("pamixsun/segformer_for_optic_disc_cup_segmentation") |
|
model = SegformerForSemanticSegmentation.from_pretrained("pamixsun/segformer_for_optic_disc_cup_segmentation") |
|
|
|
inputs = processor(image, return_tensors="pt") |
|
|
|
with torch.no_grad(): |
|
outputs = self.seg_model(**inputs) |
|
logits = outputs.logits.cpu() |
|
|
|
upsampled_logits = nn.functional.interpolate( |
|
logits, |
|
size=image.shape[:2], |
|
mode="bilinear", |
|
align_corners=False, |
|
) |
|
|
|
pred_disc_cup = upsampled_logits.argmax(dim=1)[0].numpy().astype(np.uint8) |
|
|
|
``` |
|
