Researchers propose cross-category video motion transfer
Motion Beyond Morphology targets motion transfer when source and target objects differ substantially.
Why it matters
The work addresses a core limitation in video generation systems that depend on fixed structural correspondence between a reference motion and target object. If validated, it could broaden controllable animation beyond same-category or structurally similar subjects.
The key points
- 1.Targets motion transfer across large category gaps.
- 2.Uses abstract motion views before direct conditioned generation.
- 3.OpenVMT-Dataset and OpenVMT-Bench are planned for release.
A new paper, “Motion Beyond Morphology,” proposes a framework for video motion transfer across objects with substantially different morphology, articulation, or deformation mechanisms. The method uses a two-stage approach: first learning abstract multi-granularity motion views to bootstrap cross-category video pairs, then internalizing that supervision into direct reference-video-conditioned generation. The authors also introduce OpenVMT-Dataset and OpenVMT-Bench for training and evaluation, with release planned upon acceptance.
