pytorch-enhance: Image Super-Resolution in PyTorch

Library for Minimal Modern Image Super-Resolution in PyTorch

PyTorch Enhance provides a consolidated package of popular Image Super-Resolution models, datasets, and metrics to allow for quick and painless benchmarking or for quickly adding pretrained models to your application.

Documentation

https://pytorch-enhance.readthedocs.io

Installation

pip

pip install torch-enhance

latest

git clone https://github.com/IsaacCorley/pytorch-enhance.git
cd pytorch-enhance
python setup.py install

Models

The following models are currently implemented:

SRCNN from Dong et. al Image Super-Resolution Using Deep Convolutional Networks
VDSR from Lee et al. Accurate Image Super-Resolution Using Very Deep Convolutional Networks
ESPCN from Shi et. al Real-Time Single Image and Video Super-Resolution Using an Efficient Sub-Pixel Convolutional Neural Network
SRResNet from Ledig et. al Photo-Realistic Single Image Super-Resolution Using a Generative Adversarial Network
EDSR from Lim et. al Enhanced Deep Residual Networks for Single Image Super-Resolution

import torch
import torch_enhance

# increase resolution by factor of 2 (e.g. 128x128 -> 256x256)
model = torch_enhance.models.SRResNet(scale_factor=2, channels=3)

lr = torch.randn(1, 3, 128, 128)
sr = model(x) # [1, 3, 256, 256]
