arXiv, 2024.

We propose HumanSplat, a method that predicts the 3D Gaussian Splatting properties of a human from a single input image in a generalizable way. It utilizes a 2D multi-view diffusion model and a latent reconstruction transformer with human structure priors to effectively integrate geometric priors and semantic features.

Xiaozheng Zheng, Chao Wen, Zhuo Su, Zeran Xu, Zhaohu Li, Yang Zhao, Zhou Xue
IEEE Conference on Computer Vision and Pattern Recognition (CVPR), 2024.

OHTA is a novel approach capable of creating implicit animatable hand avatars using just a single image. It facilitates 1) text-to-avatar conversion, 2) hand texture and geometry editing, and 3) interpolation and sampling within the latent space.
