针对缺乏音乐-文本配对运动数据的问题,提出TM2D方法,通过3D运动VQ-VAE混合不同数据集运动token、跨模态transformer融合双模态信息,实现高质量3D舞蹈生成,并提出新评估指标。

摘要:

我们提出了一项生成同时融合文本与音乐模态的3D舞蹈动作的新任务。与现有使用音乐等单一模态生成舞蹈动作的研究不同,我们的目标是借助文本提供的指导性信息,生成更丰富的舞蹈动作。然而,缺乏同时配有音乐和文本两种模态的配对运动数据,限制了生成融合二者的舞蹈动作的能力。为缓解这一挑战,我们提出利用3D人体运动VQ-VAE(矢量量化变分自编码器),将两个数据集的运动投影到由量化向量构成的潜空间中,有效混合来自两个不同分布数据集的运动token以进行训练。此外,我们提出一种跨模态transformer,将文本指令整合到运动生成架构中,在不降低音乐条件舞蹈生成性能的前提下生成3D舞蹈动作。为更好地评估生成运动的质量,我们引入了两个新指标,即运动预测距离(MPD)和冻结分数(FS),用于衡量生成运动的连贯性和冻结比例。大量实验表明,我们的方法能够在文本和音乐双条件下生成真实且连贯的舞蹈动作,同时保持与两种单模态方法相当的性能。代码可在https://garfield-kh.github.io/TM2D/ 获取。

英文摘要:

We propose a novel task for generating 3D dance movements that simultaneously incorporate both text and music modalities. Unlike existing works that generate dance movements using a single modality such as music, our goal is to produce richer dance movements guided by the instructive information provided by the text. However, the lack of paired motion data with both music and text modalities limits the ability to generate dance movements that integrate both. To alleviate this challenge, we propose to utilize a 3D human motion VQ-VAE to project the motions of the two datasets into a latent space consisting of quantized vectors, which effectively mix the motion tokens from the two datasets with different distributions for training. Additionally, we propose a cross-modal transformer to integrate text instructions into motion generation architecture for generating 3D dance movements without degrading the performance of music-conditioned dance generation. To better evaluate the quality of the generated motion, we introduce two novel metrics, namely Motion Prediction Distance (MPD) and Freezing Score (FS), to measure the coherence and freezing percentage of the generated motion. Extensive experiments show that our approach can generate realistic and coherent dance movements conditioned on both text and music while maintaining comparable performance with the two single modalities.
