UVIF: Unified Video and Image Representation for Boosted Video Face Forgery Detection

This repository is the official implementation of paper: Unified Video and Image Representation for Boosted Video Face Forgery Detection

Environment

• python: 3.9
• pytorch: 2.0
• mmpretrain: 1.0.0rc8

conda create -n uvif python=3.9
conda activate uvif

conda install pytorch==2.0.0 torchvision==0.15.0 torchaudio==2.0.0 pytorch-cuda=11.7 -c pytorch -c nvidia -y

pip install -U openmim

cd UVIF
mim install -e .

Dataset Preparation

We perform experiments on ForgeryNet and DFDC (preview).

We use RetinaFace to detect face bounding boxes from each video clip or static image. The processed json annotations with face regions are available at this link.

The dataset directory structure is like this:

    ├── method_B
    └── original_videos

Training and Evaluation

Taking ForgeryNet as an example:

Training

# baseline
bash tools/dist_train.sh configs_uvif/forgerynet/video_r50_forgerynet.py 2

# uvif
bash tools/dist_train.sh configs_uvif/forgerynet/uvif_r50_forgerynet.py 2

Evaluation

# single gpu
python test.py configs_uvif/forgerynet/uvif_r50_forgerynet.py pretrained/uvif_r50_forgerynet.pth

# multiple gpu
bash tools/dist_test.sh configs_uvif/forgerynet/uvif_r50_forgerynet.py pretrained/uvif_r50_forgerynet.pth 2
