MEGADance通过专家混合架构实现风格感知的3D舞蹈生成,提升舞蹈质量和风格可控性。

摘要:

音乐驱动的3D舞蹈生成近年来引起了越来越多的关注,具有在编舞、虚拟现实和创意内容创作中的广泛应用。先前的研究从音频信号中生成出有前途的逼真舞蹈动作,但传统方法往往低估了风格条件的利用,通常将其视为辅助修饰符而不是核心语义驱动因素。这种忽视影响了音乐-动作同步并破坏了舞蹈风格的连续性,特别是在复杂的节奏转换期间,从而导致视觉上不满意的后果。为了解决这一挑战,我们提出了MEGADance,一种新的音乐驱动3D舞蹈生成架构。通过将编舞一致性分解为舞蹈通用性和风格特异性,MEGADance展示了显著的舞蹈质量和强风格可控性。它由两个阶段组成:(1)高保真舞蹈量化阶段(HFDQ),通过有限标量量化(FSQ)将舞蹈动作编码为潜在表示,并通过运动-动力学约束重构它们;(2)风格感知舞蹈生成阶段(GADG),通过混合使用Mixture-of-Experts(MoE)机制与Mamba-Transformer混合主干结构,将音乐映射到潜在表示中。在FineDance和AIST++数据集上的广泛实验表明,MEGADance在定性和定量上均表现出最先进的性能。代码可在https://github.com/XulongT/MEGADance上获得。

英文摘要:

Music-driven 3D dance generation has attracted increasing attention in recent years, with promising applications in choreography, virtual reality, and creative content creation. Previous research has generated promising realistic dance movement from audio signals. However, traditional methods underutilize genre conditioning, often treating it as auxiliary modifiers rather than core semantic drivers. This oversight compromises music-motion synchronization and disrupts dance genre continuity, particularly during complex rhythmic transitions, thereby leading to visually unsatisfactory effects. To address the challenge, we propose MEGADance, a novel architecture for music-driven 3D dance generation. By decoupling choreographic consistency into dance generality and genre specificity, MEGADance demonstrates significant dance quality and strong genre controllability. It consists of two stages: (1) High-Fidelity Dance Quantization Stage (HFDQ), which encodes dance motions into a latent representation by Finite Scalar Quantization (FSQ) and reconstructs them with kinematic-dynamic constraints, and (2) Genre-Aware Dance Generation Stage (GADG), which maps music into the latent representation by synergistic utilization of Mixture-of-Experts (MoE) mechanism with Mamba-Transformer hybrid backbone. Extensive experiments on the FineDance and AIST++ dataset demonstrate the state-of-the-art performance of MEGADance both qualitatively and quantitatively.
