EBH Dataset

with Meta Reality Lab

EBH is a dataset for recovering 3D hand motion sequences from real blurry hand images and event streams, designed to capture fast hand motion under realistic visual conditions.

PROJECT EBH Dataset

Overview

Hands frequently exhibit severe motion blur because of their fast and highly articulated movement. This makes 3D hand recovery challenging: a blurry image can contain visual evidence from multiple time steps, while the exact hand configuration at a particular instant remains ambiguous.

EBH provides real blurry hand images together with corresponding event streams and 3D hand annotations, enabling research on temporally ambiguous hand motion under realistic capture conditions.

01 — REAL BLUR Captures real-world hand motion blur rather than relying only on synthetic blur generation.
02 — EVENT STREAM Provides temporally dense event information to support motion understanding under severe blur.
03 — 3D ANNOTATION Includes MANO parameters, hand meshes, and 3D keypoints for sequence-level recovery.

Visual Examples

The EBH dataset captures synchronized blurry RGB images, event-stream observations, and 3D hand annotations. The examples below illustrate both the captured visual evidence and the corresponding 3D hand reconstruction target.
