Super-resolution imaging is a class of techniques that enhance the resolution of an imaging system. In optical SR the diffraction limit of systems is transcended, while in geometrical SR the resolution of digital imaging sensors is enhanced. Wikipedia
Today's article will talk about the Top 5 Open-Source Image Super-Resolution Projects, which you can include in your next Image Processing project.
Note: In this article, we will talk about some of the not-so-famous but really good Super Resolution projects you can use in your projects. To read more about each of them, I recommend following the link given along the project.
Learning isn't just about being more competent at your job, and it is so much more than that. Datacamp allows me to learn without limits.
Datacamp provides you with the flexibility you need to take courses on your own time and learn the fundamental skills you need to transition to your successful career.
Datacamp has taught me to pick up new ideas quickly and apply them to real-world problems. While I was in my learning phase, Datacamp got me hooked with everything going on in the courses, from courses content and TA feedback to meetups events and the professor's Twitter feeds.
Here are some of my favourite courses I would highly recommend you to learn from, whenever it fits your schedule and mood. You can directly apply the concepts and skills learned from these courses to an exciting new project at work or your university.

Coming back to the topic -
1. Waifu2x — 19, 833 stars
Github | Official Documentation
Waifu2x is an open-source and free Image Super-Resolution for Anime-style art using Deep Convolution Neural Networks for images.
It supports two features for the given input image:
- 2X upscaling
- Noise reduction
It is ready to use and the demo application can be found at http://waifu2x.udp.jp/.
2. Anime4K — 12, 402 stars
Github | Official Documentation
Anime4K is a set of open-source, high-quality real-time anime upscaling/denoising algorithms that you can implement in any programming language.
The simplicity and speed of Anime4K allow the user to watch upscaled anime in real-time.
3. Singan — 2, 662 stars
Github | Official Documentation
Singan is the Official PyTorch implementation of the paper: “SinGAN: Learning a Generative Model from a Single Natural Image,” a new unconditional generative model trained on a single natural image.
Singan is trained to capture the internal distribution of patches within the image and is then able to generate high-quality, diverse samples that carry the same visual content as the image.
Here is the link to their Youtube Video.

4. Singan — 2, 422 stars
Singan is the official Tensorflow Implementation of the paper “Photo-Realistic Single Image Super-Resolution Using a Generative Adversarial Network.”
5. Image-Super-Resolution — 2, 362 stars
Github | Official Documentation
Image Super-Resolution is an open-source project to upscale and improves the quality of low-resolution images.
This project contains Keras implementations of different Residual Dense Networks for Single Image Super-Resolution (ISR) and scripts to train these networks using content and adversarial loss components.
The implemented networks include:
- The super-scaling Residual Dense Network described in Residual Dense Network for Image Super-Resolution (Zhang et al. 2018)
- The super-scaling Residual in Residual Dense Network described in ESRGAN: Enhanced Super-Resolution Generative Adversarial Networks (Wang et al. 2018)
- A multi-output version of the Keras VGG19 network for deep features extraction is used in the perceptual loss.
- A custom discriminator network based on the one described in Photo-Realistic Single Image Super-Resolution Using a Generative Adversarial Network (SRGANS, Ledig et al. 2017)
