SiPhy: Single-Image Physical Property Reasoning
Hoang Le, Joonwoo Kwon, Elkhan Ismayilzada +2
Inferring physical properties such as mass, stiffness, and elasticity from a single image is essential for simulation and embodied AI, yet most existing approaches rely on multi-vi…
Revisiting Euler-Angle Regression with Kolmogorov-Arnold Networks
Yangting Sun, Zijun Cui, Yufei Zhang
In many real-world systems, including articulated robots and biomechanical models, rotations are defined in joint space and naturally parameterized by Euler angles with bounded ran…
PAD-Hand: Physics-Aware Diffusion for Hand Motion Recovery
Elkhan Ismayilzada, Yufei Zhang, Zijun Cui
Significant advancements made in reconstructing hands from images have delivered accurate single-frame estimates, yet they often lack physics consistency and provide no notion of h…
Diffusion-based 3D Hand Motion Recovery with Intuitive Physics
Yufei Zhang, Zijun Cui, Jeffrey O. Kephart +1
While 3D hand reconstruction from monocular images has made significant progress, generating accurate and temporally coherent motion estimates from videos remains challenging, part…
Weakly-Supervised 3D Hand Reconstruction with Knowledge Prior and Uncertainty Guidance
Yufei Zhang, Jeffrey O. Kephart, Qiang Ji
Fully-supervised monocular 3D hand reconstruction is often difficult because capturing the requisite 3D data entails deploying specialized equipment in a controlled environment. We…
PhysPT: Physics-aware Pretrained Transformer for Estimating Human Dynamics from Monocular Videos
Yufei Zhang, Jeffrey O. Kephart, Zijun Cui +1
While current methods have shown promising progress on estimating 3D human motion from monocular videos, their motion estimates are often physically unrealistic because they mainly…
