 ## Overview
 [MOSIV](https://arxiv.org/abs/2603.06022) is a synthetic dataset designed for the task of **multi-object system identification from videos**, where the goal is to recover both the **4D geometry (time-varying 3D shape)** and the **physical properties** (e.g., stiffness, friction, plasticity) of multiple interacting objects directly from multi-view video observations.
