Marrying Optimal Transport and ODEs for Unified Continuous-Time 4D Reconstruction and Tracking

Liying Yang, Hao Mo, Jialun Liu +7

Existing unified 4D reconstruction and point tracking approaches typically rely on heuristic interpolations or just predict at integer timestamps, lacking kinematic coherence and f…

SIFT: Self-Imagination Fine-Tuning for Physically Plausible Motion in Video Diffusion Models

Ruoyu Wang, Jialun Liu, Huayang Huang +5

The paper introduces Self-Imagination Fine-Tuning (SIFT), a method that trains video diffusion models on their own generated videos to improve physical realism and disentangle moti…

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

Hualiang Wei, Shunran Jia, Jialun Liu +1

We present LiftAvatar, a new paradigm that completes sparse monocular observations in kinematic space (e.g., facial expressions and head pose) and uses the completed signals to dri…

Geometry-as-context: Modulating Explicit 3D in Scene-consistent Video Generation to Geometry Context

JiaKui Hu, Jialun Liu, Liying Yang +7

Scene-consistent video generation aims to create videos that explore 3D scenes based on a camera trajectory. Previous methods rely on video generation models with external memory f…
