Monocular RGB Video Neural Head Avatar with Articulated Geometry & Photorealistic Texture Figure 1. #41 opened on Sep 26 by JZArray. Such a 4D avatar will be the foundation of applications like teleconferencing in VR/AR, since it enables novel-view synthesis and control over pose and expression. Using a single photograph, our model estimates a person-specific head mesh and the associated neural texture, which encodes both local photometric and geometric details. Computer Vision and Pattern Recognition 2021 CVPR 2021 (Oral) We propose Pulsar, an efficient sphere-based differentiable renderer that is orders of magnitude faster than competing techniques, modular, and easy-to-use due to its tight integration with PyTorch. Jun Xing . 25 Sep 2022 11:12:00 The first layer is a pose-dependent coarse image that is synthesized by a small neural network. It is related to recent approaches on neural scene representation networks, as well as neural rendering methods for human portrait video synthesis and facial avatar reconstruction. Our approach is a neural rendering method to represent and generate images of a human head. It can be fast fine-tuned to represent unseen subjects given as few as 8 monocular depth images. 35 share We present dynamic neural radiance fields for modeling the appearance and dynamics of a human face.
