Deep learning has been achieving promising results across a wide range of complex task domains. However, recent advancements in deep learning have also been employed to create software which causes threats to the privacy of people and national security. One among them is deepfakes, which creates fake images as well as videos that cannot be detected as forgeries by humans. Fake speeches of world leaders can even cause threat to world stability and peace. Apart from the malicious usage, deepfakes can also be used for positive purposes such as in films for post dubbing or performing language translation. This latter case was recently used in the latest Indian election such that politician speeches can be converted to many Indian dialects across the country. This work was traditionally done using computer graphic technology and 3D models. But with advances in deep learning and computer vision, in particular GANs, the earlier methods are being replaced by deep learning methods. This research will focus on using deep neural networks for generating manipulated faces in images and videos.
This master’s thesis develops a novel architecture which can generate a full sequence of video frames given a source image and a target video. We were inspired by the works done by NVIDIA in vid2vid and few-shot vid2vid where they learn to map source video domains to target domains. In our work, we propose a unified model using LSTM based GANs along with a motion module which uses a keypoint detector to generate the dense motion. The generator network employs warping to combine the appearance extracted from the source image and the motion from the target video to generate realistic videos and also to decouple the occlusions. The training is done end-to-end and the keypoints are learnt in a self-supervised way. Evaluation is demonstrated on the recently introduced FaceForensics++ and VoxCeleb datasets.
