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

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, thus inheriting all the biases of that website, and automatically aligned and cropped using dlib. Only images under permissive licenses were collected. Various automatic filters were used to prune the set, and finally Amazon Mechanical Turk was used to remove the occasional statues, paintings, or photos of photos.

Overview

All data is hosted on Google Drive:

Path	Size	Files	Format	Description
ffhq-dataset	2.56 TB	210,014		Main folder
├ ffhq-dataset-v2.json	255 MB	1	JSON	Metadata including copyright info, URLs, etc.
├ images1024x1024	89.1 GB	70,000	PNG	Aligned and cropped images at 1024×1024
├ thumbnails128x128	1.95 GB	70,000	PNG	Thumbnails at 128×128
├ in-the-wild-images	955 GB	70,000	PNG	Original images from Flickr
├ tfrecords	273 GB	9	tfrecords	Multi-resolution data for StyleGAN and StyleGAN2
└ zips	1.28 TB	4	ZIP	Contents of each folder as a ZIP archive.

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, 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. 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.

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 paper, use the following options:

python download_ffhq.py \
    --source-dir 
   
     \
    --align --no-rotation --random-shift 0.2 --no-padding --retry-crops

Privacy

When collecting the data, we were careful to only include photos that – to the best of our knowledge – were intended for free use and redistribution by their respective authors. That said, we are committed to protecting the privacy of individuals who do not wish their photos to be included.

To find out whether your photo is included in the Flickr-Faces-HQ dataset, please click this link to search the dataset with your Flickr username.

To get your photo removed from the Flickr-Faces-HQ dataset:

Go to Flickr and do one of the following:
- Tag the photo with no_cv to indicate that you do not wish it to be used for computer vision research.
- Change the license of the photo to None (All rights reserved) or any Creative Commons license with NoDerivs to indicate that you do not want it to be redistributed.
- Make the photo private, i.e., only visible to you and your friends/family.
- Get the photo removed from Flickr altogether.
Contact [email protected]. Please include your Flickr username in the email.
We will check the status of all photos from the particular user and update the dataset accordingly.
