| ## Flickr-Faces-HQ Dataset (FFHQ) | |
|  | |
|  | |
|  | |
|  | |
|  | |
|  | |
| Flickr-Faces-HQ (FFHQ) is a high-quality image dataset of human faces, originally created as a benchmark for generative adversarial networks (GAN): | |
| > **A Style-Based Generator Architecture for Generative Adversarial Networks**<br> | |
| > Tero Karras (NVIDIA), Samuli Laine (NVIDIA), Timo Aila (NVIDIA)<br> | |
| > https://arxiv.org/abs/1812.04948 | |
| The dataset consists of 70,000 high-quality PNG images at 1024×1024 resolution and contains considerable variation in terms of age, ethnicity and image background. It also has good coverage of accessories such as eyeglasses, sunglasses, hats, etc. The images were crawled from [Flickr](https://www.flickr.com/), thus inheriting all the biases of that website, and automatically aligned and cropped using [dlib](http://dlib.net/). Only images under permissive licenses were collected. Various automatic filters were used to prune the set, and finally [Amazon Mechanical Turk](https://www.mturk.com/) was used to remove the occasional statues, paintings, or photos of photos. | |
| Please note that this dataset is not intended for, and should not be used for, development or improvement of facial recognition technologies. For business inquiries, please visit our website and submit the form: [NVIDIA Research Licensing](https://www.nvidia.com/en-us/research/inquiries/) | |

| High-level statistics: | |
|  | |
| For use cases that require separate training and validation sets, we have appointed the first 60,000 images to be used for training and the remaining 10,000 for validation. In the [StyleGAN paper](https://arxiv.org/abs/1812.04948), however, we used all 70,000 images for training. | |
| We have explicitly made sure that there are no duplicate images in the dataset itself. However, please note that the `in-the-wild` folder may contain multiple copies of the same image in cases where we extracted several different faces from the same image. | |
| ## Download script | |
| You can either grab the data directly from Google Drive or use the provided [download script](./download_ffhq.py). The script makes things considerably easier by automatically downloading all the requested files, verifying their checksums, retrying each file several times on error, and employing multiple concurrent connections to maximize bandwidth. | |
| ``` | |
| > python download_ffhq.py -h | |
| usage: download_ffhq.py [-h] [-j] [-s] [-i] [-t] [-w] [-r] [-a] | |
| [--num_threads NUM] [--status_delay SEC] | |
| [--timing_window LEN] [--chunk_size KB] | |
| [--num_attempts NUM] | |
| Download Flickr-Face-HQ (FFHQ) dataset to current working directory. | |
| optional arguments: | |
| -h, --help show this help message and exit | |
| -j, --json download metadata as JSON (254 MB) | |
| -s, --stats print statistics about the dataset | |
| -i, --images download 1024x1024 images as PNG (89.1 GB) | |
| -t, --thumbs download 128x128 thumbnails as PNG (1.95 GB) | |

| --source-dir DIR where to find already downloaded FFHQ source data | |
| ``` | |
| ``` | |

| ``` | |
| The script also serves as a reference implementation of the automated scheme that we used to align and crop the images. Once you have downloaded the in-the-wild images with `python download_ffhq.py --wilds`, you can run `python download_ffhq.py --align` to reproduce exact replicas of the aligned 1024×1024 images using the facial landmark locations included in the metadata. | |
| ### Reproducing the unaligned FFHQ | |
| To reproduce the "unaligned FFHQ" dataset as used in the [Alias-Free Generative Adversarial Networks](https://arxiv.org/abs/2106.12423) paper, use the following options: | |
| ``` | |
| python download_ffhq.py \ | |
| --source-dir <path/to/downloaded/ffhq> \ | |
| --align --no-rotation --random-shift 0.2 --no-padding --retry-crops | |
| ``` | |
