Neural Voxel Dynamics: Learning Volumetric Feature Advection for 3D Physics in V-JEPA Latent Space
Zican Wang, Niloy Mitra
We present Neural Voxel Dynamics, a self-supervised framework for learning 3D latent dynamics from monocular video. While generative video models now produce visually compelling mo…
Learning to Solve PDEs on Neural Shape Representations
Lilian Welschinger, Yilin Liu, Zican Wang +1
Solving partial differential equations (PDEs) on shapes underpins many shape analysis and engineering tasks; yet, prevailing PDE solvers operate on polygonal/triangle meshes while…
Stochastic Gradient Estimation for Higher-order Differentiable Rendering
Zican Wang, Michael Fischer, Tobias Ritschel
We derive methods to compute higher order differentials (Hessians and Hessian-vector products) of the rendering operator. Our approach is based on importance sampling of a convolut…
SCREENER: A general framework for task-specific experiment design in quantitative MRI
Tianshu Zheng, Zican Wang, Timothy Bray +3
Quantitative magnetic resonance imaging (qMRI) is increasingly investigated for use in a variety of clinical tasks from diagnosis, through staging, to treatment monitoring. However…
