# Real-ESRGAN
|
10 |
+
|
11 |
+
PyTorch implementation of a Real-ESRGAN model trained on custom dataset. This model shows better results on faces compared to the original version. It is also easier to integrate this model into your projects.
|
12 |
+
|
13 |
+
Real-ESRGAN is an upgraded ESRGAN trained with pure synthetic data is capable of enhancing details while removing annoying artifacts for common real-world images.

|
21 |
+
Code for using model you can obtain in our [repo](https://github.com/LikeRainDay/Real-ESRGAN).

+
from RealESRGAN import RealESRGAN
|
27 |
+
device = torch.device('cuda' if torch.cuda.is_available() else 'cpu')
|
28 |
+
model = RealESRGAN(device, scale=4)
|
29 |
+
model.load_weights('weights/RealESRGAN_x4.pth', download=True)
|
30 |
+
path_to_image = 'inputs/lr_image.png'
|
31 |
+
image = Image.open(path_to_image).convert('RGB')
|
32 |
+
sr_image = model.predict(image)
|
33 |
+
sr_image.save('results/sr_image.png')
