+# SeeU45 Dataset
+
+This repository contains the SeeU45 dataset introduced in the paper [SeeU: Seeing the Unseen World via 4D Dynamics-aware Generation](https://huggingface.co/papers/2512.03350).
+
+SeeU is a framework that learns continuous 4D dynamics from sparse and monocular 2D frames, enabling the generation of unseen visual content through a 2D $\to$ 4D $\to$ 2D learning process.
