dc.description.abstract | The recent advance in generative adversarial networks has shown promising results in solving the problem of head reenactment. It aims to generate novel images with altered poses and emotions while preserving the identity of a human head from a single photo. Current approaches have limitations, making them inapplicable for real-world applications. Specifically, most algorithms are computationally expensive, have no apparent tools for manual image manipulation, require audio or take multiple input images to generate novel images. Our method addresses the single-shot face reenactment problem with an end-toend algorithm. The proposed method utilizes head 3D morphable model (3DMM) parameters to encode identity, pose, and expression. With the proposed approach, the pose and emotion of a person on an image is changed by manipulating its 3DMM parameters. Our work consists of a face mesh prediction network and a GAN-based renderer. A predictor is a neural network with simple encoder architecture that regresses 3D mesh parameters. A renderer is a GAN network with warping and rendering submodules that renders images from a single source image and target image 3DMM parameters. This work proposes a novel head reenactment framework that is computationally efficient and uses 3DMM parameters that are easy to alter, making the proposed method applicable in real-life applications. It is first to our knowledge approach that simultaneously solves two of these problems: 3DMM parameters prediction and face reenactment, and benefits from both. | uk |
