Drawing Humans with Neural Networks

Abstract

I will present two recent works from Samsung AI Center on realistic rendering of humans with deep convolutional neural networks. The first work develops an approach that creates photorealistic personalized head avatars from few images of a person (few-shot avatars). The resulting avatars can be driven by facial keypoints. To be able to capture a person's appearance from few images, this system uses a strong prior learned from a large and diverse dataset of human videos of different people. The second work develops a system for capturing the static appearance of a single person in 3D (a 3D portrait). The new system is in many ways similar to standard 3D modeling framework, however it uses a point cloud geometric representation together with a deep neural rendering network. Such neural point-based graphics system builds a 3D model that can be rendered with photorealistic quality from new viewpoints, without performing the brittle step of meshing / surface estimation.
