# Real-ESRGAN

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.

> This is not an official implementation. We partially use code from the [original repository](https://github.com/xinntao/Real-ESRGAN)

Real-ESRGAN is an upgraded [ESRGAN](https://arxiv.org/abs/1809.00219) trained with pure synthetic data is capable of enhancing details while removing annoying artifacts for common real-world images. 

You can try it in [google colab](https://colab.research.google.com/drive/1YlWt--P9w25JUs8bHBOuf8GcMkx-hocP?usp=sharing) [![Open In Colab](https://colab.research.google.com/assets/colab-badge.svg)](https://colab.research.google.com/drive/1YlWt--P9w25JUs8bHBOuf8GcMkx-hocP?usp=sharing)

### Installation

```bash

pip install git+https://github.com/sberbank-ai/Real-ESRGAN.git

```

### Usage

---

Basic usage:

```python

import torch

from PIL import Image

import numpy as np

from RealESRGAN import RealESRGAN

device = torch.device('cuda' if torch.cuda.is_available() else 'cpu')

model = RealESRGAN(device, scale=4)

model.load_weights('weights/RealESRGAN_x4.pth', download=True)

path_to_image = 'inputs/lr_image.png'

image = Image.open(path_to_image).convert('RGB')

sr_image = model.predict(image)

sr_image.save('results/sr_image.png')

```
