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.

Learning to Generate Conditional Tri-plane for 3D-aware Expression Controllable Portrait Animation

Researchers present Export3D, a new AI method for creating 3D-aware portrait animations from a single image with controllable facial expressions and camera angles. The technique uses a tri-plane generator and contrastive pre-training to avoid unwanted appearance changes when transferring expressions between different identities.

LiftAvatar: Kinematic-Space Completion for Expression-Controlled 3D Gaussian Avatar Animation

LiftAvatar is a new AI system that enhances 3D avatar animation by completing sparse monocular video observations in kinematic space using expression-controlled video diffusion Transformers. The technology addresses limitations in 3D Gaussian Splatting-based avatars by generating high-quality, temporally coherent facial expressions from single or multiple reference images.

BiMotion: B-spline Motion for Text-guided Dynamic 3D Character Generation

Researchers introduce BiMotion, a new AI framework that uses B-spline curves to generate high-quality 3D character animations from text descriptions. The method addresses limitations in existing approaches by using continuous motion representation instead of discrete frames, enabling more expressive and coherent character movements.
