摘要:

本文通过聚焦2D空间,提出了一条实现通用人体运动生成的新路径。传统方法主要在3D中生成人体运动,这些运动虽然细致且逼真,但往往受限于可用3D运动数据在规模和多样性方面的覆盖范围。为解决这些局限,我们利用2D运动数据的广泛可得性,提出了 Holistic-Motion2D,这是首个用于2D全身运动生成的综合性大规模基准,包含超过100万个野外运动序列,每个序列均配有高质量的全身/部分姿态标注和文本描述。值得注意的是,Holistic-Motion2D 比此前最大的3D运动数据集大十倍。我们还提出了一种基线方法,其特点是采用创新的全身部位感知注意力和置信度感知建模技术,专为2D文本驱动的全身运动生成而设计,即 Tender。大量实验证明了 Holistic-Motion2D 和 Tender 在生成富有表现力、多样化且逼真的人体运动方面的有效性。我们还强调了2D运动在多种下游应用中的效用,以及其提升至3D运动的潜力。项目页面链接为:https://holistic-motion2d.github.io。

英文摘要:

In this paper, we introduce a novel path to $\textit{general}$ human motion generation by focusing on 2D space. Traditional methods have primarily generated human motions in 3D, which, while detailed and realistic, are often limited by the scope of available 3D motion data in terms of both the size and the diversity. To address these limitations, we exploit extensive availability of 2D motion data. We present $\textbf{Holistic-Motion2D}$, the first comprehensive and large-scale benchmark for 2D whole-body motion generation, which includes over 1M in-the-wild motion sequences, each paired with high-quality whole-body/partial pose annotations and textual descriptions. Notably, Holistic-Motion2D is ten times larger than the previously largest 3D motion dataset. We also introduce a baseline method, featuring innovative $\textit{whole-body part-aware attention}$ and $\textit{confidence-aware modeling}$ techniques, tailored for 2D $\underline{\text T}$ext-driv$\underline{\text{EN}}$ whole-bo$\underline{\text D}$y motion gen$\underline{\text{ER}}$ation, namely $\textbf{Tender}$. Extensive experiments demonstrate the effectiveness of $\textbf{Holistic-Motion2D}$ and $\textbf{Tender}$ in generating expressive, diverse, and realistic human motions. We also highlight the utility of 2D motion for various downstream applications and its potential for lifting to 3D motion. The page link is: https://holistic-motion2d.github.io.
