Expressive Gaussian Human Avatars from Monocular RGB Video

NeurIPS 2024poster

Nuanced expressiveness, especially through detailed hand and facial expressions, is pivotal for enhancing the realism and vitality of digital human representations. In this work, we aim to learn expressive human avatars from a monocular RGB video; a setting that introduces new challenges in capturin…

Neural Fields with Hard Constraints of Arbitrary Differential Order

NeurIPS 2023poster

While deep learning techniques have become extremely popular for solving a broad range of optimization problems, methods to enforce hard constraints during optimization, particularly on deep neural networks, remain underdeveloped. Inspired by the rich literature on meshless interpolation and its ext…

D^2NeRF: Self-Supervised Decoupling of Dynamic and Static Objects from a Monocular Video

NeurIPS 2022accept

Given a monocular video, segmenting and decoupling dynamic objects while recovering the static environment is a widely studied problem in machine intelligence. Existing solutions usually approach this problem in the image domain, limiting their performance and understanding of the environment. We in…
