Egor Zakharov

I am a Postdoc at ETH Zurich AIT lab. My research interests include computer vision and graphics for the problems of 3D reconstruction and image animation.

I received my Ph.D. from Skoltech, under the supervision of Victor Lempitsky. During my Ph.D., I also was a Lead Research Scientist at Samsung AI Center.

We improve existing surface reconstruction methods using a plug-and-play hybrid representation, achieving up-to 18% improvement in reconstruction quality and approx. 2x faster convergence speed.

Realistic One-shot Mesh-based Head Avatars

We create animatable 3D head reconstructions in the form of a rigged mesh from a single image by leveraging facial priors and differentiable rendering of in-the-wild video data.

MegaPortraits: One-shot Megapixel Neural Head Avatars

Leveraging a large corpus of weakly annotated video data to achieve the realistic synthesis of human heads in a few-shot scenario using meta-learning and GAN-based training.

Textured Neural Avatars
Aliaksandra Shysheya, Egor Zakharov, Kara-Ali Aliev, Renat Bashirov, Egor Burkov, Karim Iskakov, Aleksei Ivakhnenko, Yury Malkov, Igor Pasechnik, Dmitry Ulyanov, Alexander Vakhitov, Victor Lempitsky
CVPR, 2019   (Oral Presentation)   top 5.6% of the submissions
project page / arXiv

We integrated classical and neural rendering approaches to achieve high robustness of the avatar renders to the poses and views unseen during training.

Image Manipulation with Perceptual Discriminators
Diana Sungatullina, Egor Zakharov, Dmitry Ulyanov, Victor Lempitsky
ECCV, 2018
project page / arXiv

We combine the GAN-based and perceptual losses in a single training method, which primarily excels at the task of facial attribute manipulation.
