XmoPipe: A Pipeline for Large-Scale In-the-Wild Human Motion Dataset Construction

XmoPipe is a scalable pipeline that constructs large-scale human motion datasets by extracting 3D body and facial motion from unconstrained online videos, combined with automated textual descriptions. The system demonstrates that motion models trained on this in-the-wild data achieve performance comparable to traditional marker-based motion capture datasets while offering superior scalability and diversity.

Text Dictates, Music Decorates: Energy-based Attention for Editable Dance Motion Generation

Researchers introduce STREAM, a diffusion transformer model that generates danceable choreography from text and music by decoupling their conditioning pathways, preventing acoustic dominance from overwhelming semantic control. The team releases Motorica++, an enhanced dataset with semantic annotations, and proposes new evaluation metrics (Exchange Evaluation Protocol and Editable Dance Score) to measure zero-shot editability in generative motion synthesis.

Cross-Axis Feature Fusion with Joint-Wise Motion Difference Prediction for Text-Based 3D Human Motion Editing

Researchers propose a novel deep learning architecture for text-based 3D human motion editing that uses cross-axis feature fusion and joint-wise motion prediction to better understand which body joints should be modified and when. The method achieves state-of-the-art results on the MotionFix dataset by combining two specialized transformers that process temporal and spatial dimensions independently before fusion.
