New framework uses 3D trajectories for precise skeleton animation

Researchers have developed ACT, a novel framework for creating precise skeleton animations controlled by 3D trajectories. This approach utilizes skeletons as an efficient representation and extracts motion guidance from monocular video, avoiding the entanglement of appearance and background found in other methods. ACT employs a Routed Trajectory Injector with prior-guided hard routing, global routing, and local windowed cross-attention to ensure accurate skeleton-to-mesh correspondence, full-body motion awareness, and fine-grained temporal alignment, outperforming existing methods in fidelity and consistency.
