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…
