RGB-D Segment Egocentric Bodies Dataset

Overview

The RGB-D Segment Egocentric Bodies Dataset is a multi-modal dataset designed for egocentric body segmentation and depth-aware perception. It contains synchronized RGB images, real depth maps, segmentation masks, and synthetic depth data, captured from an egocentric point of view.
The dataset is intended to support research in egocentric vision, XR/VR/AR, human–computer interaction, and depth-aware computer vision.

Dataset Description

The dataset is an extension of the EgoBodies Dataset (please refer to https://arxiv.org/pdf/2207.01296 for more information), with depth frames. We provide two versions of depth: real depth images acquired with different sensors: RealSense D435, Realsense L515. Synthetic detph were estimated using Depth-Anything by Yang et al (2024). It is composed of more than 40 different users, in wild scenarios.

Intended Use

This dataset is suitable for:

• Egocentric human / body-part segmentation
• Depth-aware perception models
• XR avatar embodiment and telepresence
• Mixed-reality interaction research
• Training and benchmarking RGB-D models

Example Usage

from PIL import Image
import numpy as np
import os

def load_sample(root, split, idx):
    base = os.path.join(root, split)
    rgb = Image.open(os.path.join(base, "images", f"{idx}.png"))
    depth = Image.open(os.path.join(base, "depths", f"{idx}.png"))
    mask = Image.open(os.path.join(base, "masks", f"{idx}.png"))
    synth = Image.open(os.path.join(base, "synthetic_depths", f"{idx}.png"))
    return rgb, depth, mask, synth
