Linear Multi-granular Body Modeling for Text-Driven Motion Generation proposes HiSTF Mamba, a linear-time framework that combines Dual‑Spatial Mamba, Bi‑Temporal Mamba, and a Dynamic Spatiotemporal Fusion Module to model both part‑level and whole‑body dynamics. The approach captures local joint dynamics and global coordination in parallel, encodes short‑term and long‑term motion details bidirectionally, and removes redundant features to produce an expressive spatiotemporal representation. Experiments on HumanML3D and KIT‑ML show that HiSTF Mamba achieves higher generation fidelity and semantic alignment while using far fewer parameters than existing segment‑based architectures.

BiMoGen introduces a unified masked discrete diffusion framework for bidirectional motion‑text generation, addressing limitations of autoregressive models by allowing iterative bidirectional prediction. The method employs a two‑stage training strategy—Decoupled Uni‑ and Cross‑Modal Training followed by supervised fine‑tuning—to establish cross‑modal correspondence and specialize for bidirectional generation. To mitigate train‑test mismatch, Generation‑Aware Self‑Correction exposes the model to its own predictions during training and applies correction passes early in sampling to refine unmasked tokens, achieving competitive results on HumanML3D and KIT‑ML.

The paper introduces Timo, a kinematics-aware multimodal diffusion transformer designed for human motion generation. Timo employs fully shared multimodal attention, flow matching, and geometric/rotational-kinematics supervision to better coordinate articulated motion, and uses a two-stage curriculum to align motion with text captions. The authors also present a new benchmark of 40,025 clips from six datasets, showing that Timo outperforms state‑of‑the‑art methods, achieving a 40.8% relative improvement over Kimodo on average.

BiMoGen introduces a unified masked discrete diffusion framework for bidirectional motion‑text generation, addressing the limitations of autoregressive models in capturing bidirectional dependencies between language and motion. The approach employs a two‑stage training strategy—decoupled uni‑ and cross‑modal pretraining followed by supervised fine‑tuning—to establish robust cross‑modal correspondence, and incorporates Generation‑Aware Self‑Correction to mitigate error propagation during inference. Experiments on HumanML3D and KIT‑ML show competitive performance on both text‑to‑motion and motion‑to‑text tasks, demonstrating the effectiveness of the proposed training and correction mechanisms.

VTrajEmbed is an embedding model that aligns text with video object trajectories by decomposing videos into individual trajectories and embedding each trajectory separately. It introduces a Slow‑Fast Trajectory Encoding dual‑branch architecture that captures high‑frequency motion and scene context, and a Mask‑Guided Contrastive Learning objective that prevents false negatives during training. The model is evaluated on a new trajectory‑level benchmark, Text2Traj‑Bench, and outperforms existing large‑language‑model embeddings by significant margins on both text‑to‑trajectory and trajectory‑to‑text retrieval tasks.

The paper introduces a unified conditional-flow framework that integrates text-driven motion generation, semantic editing, and intra-structural retargeting into a single rectified-flow model. By treating editing as a change in semantic condition and retargeting as a change in skeletal condition, the approach eliminates fragmented pipelines and allows a single model to perform generation, zero‑shot editing, and zero‑shot retargeting on articulated 3D motion data. Experiments on SnapMoGen and a Mixamo subset demonstrate that the model can handle all three tasks without task‑specific fine‑tuning, preserving both motion semantics and skeletal structure.
