DeepFakesON-Phys: DeepFakes Detection based on Heart Rate Estimation

Overview

DeepFakesON-Phys is DeepFake detection framework based on physiological measurement. In particular, it considers information related to the heart rate using remote photoplethysmography (rPPG). DeepFakesON-Phys uses a Convolutional Attention Network (CAN), which extracts spatial and temporal information from video frames, analyzing and combining both sources to better detect fake videos.

DeepFakesONPhys has been experimentally evaluated using the latest public databases in the field: Celeb-DF and DFDC. The results achieved, above 98% AUC (Area Under the Curve) on both databases, outperform the state of the art and prove the success of fake detectors based on physiological measurement to detect the latest DeepFake videos.

Access

-- Configuring environment in Windows:

1. Installing Conda: https://conda.io/projects/conda/en/latest/user-guide/install/windows.html

Update Conda in the default environment:

conda update conda
conda upgrade --all

Create a new environment:

conda create -n [env-name]

Activate the environment:

conda activate [env-name]

2) Installing dependencies in your environment:

Install Tensorflow and all its dependencies:

pip install tensorflow

Install OpenCV:

conda install -c conda-forge opencv

3) If you want to use a CUDA compatible GPU for faster predictions you will need CUDA and the Nvidia drivers installed in your computer: https://docs.nvidia.com/deeplearning/sdk/cudnn-install/

-- Using DeepFakesON-Phys for predicting scores:

1. Download or clone the repository.

2. You have to run the vid_to_deepframes_rawframes.py script : it preprocesses the video sequences to obtain the raw normalized frames and the difference frames to feed DeepFakesON-Phys.

3. Run the DeepFakesON-Phys_extract_preditions.py script: it makes inference with the processed input and returns a fake/genuine score for each frame in the video and saves them in the scores.txt file. You can combine the individual scores as you wish, e.g., by temporal windows, using some kind of temporal integration, etc.
