Real Face Foundation Representation Learning for Generalized Deepfake Detection

This repository is the official implementation of Real Face Foundation Representation Learning for Generalized Deepfake Detection.

The paper is published at Pattern recognition in Dec 2024.

Overview

In this study, we propose Real Face Foundation Representation Learning (RFFR), which aims to learn a general representation from large-scale real face datasets and detect potential artifacts outside the distribution of RFFR.

Preparations

• To install requirements:

pip install -r requirements.txt

• Download datasets at FaceForensics++, ForgeryNet, Celeb-DF, etc.

• Run face detection. With cropped face images, generate json files in the following format:

[
    {
        "path": "path/to/image_0.png",
        "label": 0
    },

    {
        "path": "path/to/image_1.png",
        "label": 1
    },

    ...
]

• Link the json files in the config files to load the data. You can also just modify the dataset files to load the images in any other ways you want.

Training

Make sure to specify paths to labels, pretrained models, as well as hyperparameters in rffr_classifier/configs/config.py and rffr_generative/configs/config.py.

To train the generative model that produces residuals:

cd rffr_generative
python train.py

To train the classifier:

cd rffr_classifier
python train.py

Evaluation

Specify models to test in the aforementioned config files.

View demos of the generative model's output by running:

cd rffr_generative
python evaluate.py

Test the deepfake detector by running:

cd rffr_classifier
python test.py
