SceneTracker: Long-term Scene Flow Estimation Network

no code implementations29 Mar 2024 Bo wang, Jian Li, Yang Yu, Li Liu, Zhenping Sun, Dewen Hu

Considering the complementarity of scene flow estimation in the spatial domain's focusing capability and 3D object tracking in the temporal domain's coherence, this study aims to address a comprehensive new task that can simultaneously capture fine-grained and long-term 3D motion in an online manner: long-term scene flow estimation (LSFE).
