Flex4DHuman: Flexible Multi-view Video Diffusion for 4D Human Reconstruction

Jen-Hao Cheng, Yipeng Wang, Hao Zhang +2

We present Flex4DHuman, a multi-view video diffusion model that transforms a monocular or sparse multi-view video of a dynamic subject into synchronized dense multi-view videos usi…

World Tracing: Generative Pixel-Aligned Geometry Beyond the Visible

Hao Zhang, Mohamed El Banani, Jen-Hao Cheng +6

Image-to-3D methods often trade off faithfulness and completeness: depth estimators are anchored to input pixels but stop at the visible surface, while image-to-3D models generate…

PAD3R: Pose-Aware Dynamic 3D Reconstruction from Casual Videos

Ting-Hsuan Liao, Haowen Liu, Yiran Xu +3

We present PAD3R, a method for reconstructing deformable 3D objects from casually captured, unposed monocular videos. Unlike existing approaches, PAD3R handles long video sequences…

Tactile DreamFusion: Exploiting Tactile Sensing for 3D Generation

Ruihan Gao, Kangle Deng, Gengshan Yang +2

3D generation methods have shown visually compelling results powered by diffusion image priors. However, they often fail to produce realistic geometric details, resulting in overly…

Agent-to-Sim: Learning Interactive Behavior Models from Casual Longitudinal Videos

Gengshan Yang, Andrea Bajcsy, Shunsuke Saito +1

We present Agent-to-Sim (ATS), a framework for learning interactive behavior models of 3D agents from casual longitudinal video collections. Different from prior works that rely on…

DressRecon: Freeform 4D Human Reconstruction from Monocular Video

Jeff Tan, Donglai Xiang, Shubham Tulsiani +2

We present a method to reconstruct time-consistent human body models from monocular videos, focusing on extremely loose clothing or handheld object interactions. Prior work in huma…
