# PaddleGAN

PaddleGAN provides developers with high-performance implementation of classic and SOTA Generative Adversarial Networks, and supports developers to quickly build, train and deploy GANs for academic, entertainment and industrial usage.

GAN-Generative Adversarial Network, was praised by "the Father of Convolutional Networks"  **Yann LeCun (Yang Likun)**  as **[One of the most interesting ideas in the field of computer science in the past decade]**. It's the one research area in deep learning that AI researchers are most concerned about.

## Quick Start

* Please refer to the [installation document](./docs/en_US/install.md) to make sure you have installed PaddlePaddle and PaddleGAN correctly.

* Get started through ppgan.app interface:

   ```python
   from ppgan.apps import RealSRPredictor
   sr = RealSRPredictor()
   sr.run("docs/imgs/monarch.png")
   ```
* More applications, please refer to [ppgan.apps apis](./docs/en_US/apis/apps.md)

### PaddleGAN Special Interest Group（SIG）

It was first proposed and used by [ACM（Association for Computing Machinery)](https://en.wikipedia.org/wiki/Association_for_Computing_Machinery) in 1961. Top International open source organizations including [Kubernates](https://kubernetes.io/) all adopt the form of SIGs, so that members with the same specific interests can share, learn knowledge and develop projects. These members do not need to be in the same country/region or the same organization, as long as they are like-minded, they can all study, work, and play together with the same goals~

PaddleGAN SIG is such a developer organization that brings together people who interested in GAN. There are frontline developers of PaddlePaddle, senior engineers from the world's top 500, and students from top universities at home and abroad.

We are continuing to recruit developers interested and capable to join us building this project and explore more useful and interesting applications together.

SIG contributions:

- [zhen8838](https://github.com/zhen8838): contributed to AnimeGANv2.
- [Jay9z](https://github.com/Jay9z): contributed to DCGAN and updated install docs, etc.
- [HighCWu](https://github.com/HighCWu): contributed to c-DCGAN and WGAN. Support to use `paddle.vision.datasets`.
- [hao-qiang](https://github.com/hao-qiang) & [ minivision-ai ](https://github.com/minivision-ai): contributed to the photo2cartoon project.
