A Real-ESRGAN model trained on a custom dataset

Real-ESRGAN-inference

This is an unofficial repository 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.

You can try it in google colab

Installation

---

1. Clone repo

   git clone https://github.com/boomb0om/Real-ESRGAN-colab
   cd Real-ESRGAN-colab

2. Install requirements

   pip install -r requirements.txt

3. Download pretrained weights and put them into weights/ folder

Usage

---

Basic example:

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')

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')
