M-PhyGs: Multi-Material Object Dynamics from Video

Norika Wada, Kohei Yamashita, Ryo Kawahara +1

Knowledge of the physical material properties governing the dynamics of a real-world object becomes necessary to accurately anticipate its response to unseen interactions. Existing…

Spatial Polarization Multiplexing: Single-Shot Invisible Shape and Reflectance Recovery

Tomoki Ichikawa, Ryo Kawahara, Ko Nishino

We propose spatial polarization multiplexing (SPM) for joint sensing of shape and reflectance of a static or dynamic deformable object, which is also invisible to the naked eye. Pa…

SHeaP: Self-Supervised Head Geometry Predictor Learned via 2D Gaussians

Liam Schoneveld, Zhe Chen, Davide Davoli +4

Accurate, real-time 3D reconstruction of human heads from monocular images and videos underlies numerous visual applications. As 3D ground truth data is hard to come by at scale, p…
