Anonymize video

The purpose of this script is to detect faces in an input video file and replace them with imaginary faces.

Random faces are generated by the "Progressive growing of GANs" DNN model pre-trained by NVIDIA. Each frame of the input video is extracted using OpenCV and analyzed using dlib to detect faces and facial landmarks. Each face is then wrapped with one of the faces imagined by the GAN.

Usage

Clone this repository:

git clone https://github.com/FlorentRevest/anonymize-video

Install the required python3 modules: (Note: You will need CUDA)

pip3 install -r requirements.txt

Download the progressive growing of GANs model from NVIDIA. And save it under models/karras2018iclr-celebahq-1024x1024.pkl

Download the facial landmarks detector model from dlib. Extract it and save it under models/shape_predictor_68_face_landmarks.dat

Run the script on an input video:

./anonymize-video.py input.mp4 output.avi

Demo files

Two examples of input videos can be downloaded from here and here

Troubleshooting

If this scripts stops early with an error "0 faces found in a dreamed image. Aborting." just re-run the script once again. This happens from time to time, when the Progressive GAN network generates faces that are not recognized by dlib
