Ego-Exo4D Human Meshes Dataset: 4D Human Motion Reconstruction for Ego-Exo Captures

Ego-Exo4D is a large-scale dataset that offers synchronized egocentric and multi-view exocentric video for applications such as skill learning, procedural activity understanding, and embodied AI. The original dataset only includes sparse 3D human pose annotations, making dense motion reconstruction challenging. To address this, the authors introduce Ego-Exo4D-HM, a new dataset containing 4D human motion reconstructions for the Ego-Exo4D captures, along with a reconstruction pipeline and accompanying code and documentation.

MINT: A Unified Model for World-Space Camera and Hand Motion Estimation from Scalable Egocentric Pipeline Supervision

MINT is a foundation model that directly predicts world-space two-hand trajectories from egocentric RGB video, jointly estimating camera motion, hand states, and hand presence in a single spatiotemporal representation. It uses an open-source labeling pipeline, EGOPIPELINE, to generate large-scale pseudo-labels for pretraining, followed by fine-tuning on a small set of high-quality joint annotations. The model outperforms existing multi-stage approaches in accuracy and speed, and generalizes zero‑shot to unseen egocentric datasets.
