Face-Cutout

Code for the paper Towards Solving the DeepFake Problem: An Analysis on Improving DeepFake Detection Using Dynamic Face Augmentation Sowmen Das, Selim Seferbekov, Arup Datta, Md. Saiful Islam, Md. Ruhul Amin; Proceedings of the IEEE/CVF International Conference on Computer Vision (ICCV) Workshops, 2021, pp. 3776-3785. [paper] [presentation]

Sensory cutout uses MTCNN face detector. Convex-hull cutout uses DLIB face detector.

Files

• face_cutout.py containes implementation of Face Cutout
• See face_cutout_demo.ipynb to run face-cutout on sample images
• libs directory contains weights for DLIB Face detector.

Instructions

   $ pip3 install virtualenv
   $ virtualenv -p python3 venv 
   $ source venv/bin/activate
   $ pip install -r requirements.txt

Training

Organize the data in the following structure. Each dataset will have the folders :

• face_crops containing face images cropped from the video.
• diffs containing difference masks for the fake videos. It is better to precalculate these masks for faster training. Otherwise, they will be determined during runtime.
• original_landmarks containing MTCNN landmarks for the original frames. Data is stored as .npy numpy format.
