🌍 Sign Language Dataset Hub

[] [] []

A curated, verified catalog of 73+ sign language datasets covering 26 sign languages — the most comprehensive open collection for sign language recognition (SLR) research, gesture recognition, deaf community technology, and assistive AI development.

🎯 Mission

To democratize access to sign language technology by providing:

Verified dataset links — every URL checked, sample counts from original sources
Working tools for loading, visualizing, and processing data
Demo datasets for learning and prototyping
Proper attribution to all data creators

Helping developers, researchers, and the deaf community build better assistive technology.

✅ Sample counts are from the original publication, not estimated
✅ Every dataset has a citation or credit to its creator
✅ No placeholder or fabricated links exist in the active catalog
✅ Datasets we couldn't verify are excluded (not listed with fake info)

🚀 Quick Start

Clone & Setup

git clone https://github.com/rudra496/SignLanguage-Dataset-Hub.git
cd SignLanguage-Dataset-Hub
pip install -r requirements.txt

Use the Demo Data (Bangla Sign Language Sensor Data)

from scripts.data_loader import BdSLSensorGloveDataset

# Load demo sensor data (4,824 samples)
dataset = BdSLSensorGloveDataset(split='train')
print(f"Loaded {len(dataset)} samples, 36 gesture classes")

sample = dataset[0]
print(f"Gesture: {sample['gesture_name']}")
print(f"Sensors shape: {sample['sensors'].shape}")

Visualize Sensor Data

python tools/visualize.py --data data/bdsl/BdSL-Sensor-Glove/

Browse Programmatically

import pandas as pd
df = pd.read_csv('datasets_catalog.csv')

# Filter by language
asl = df[df['language_code'] == 'ASL']
print(asl[['name', 'samples', 'source_url']])

# Filter by modality
video = df[df['modality'].str.contains('Video')]
print(f"Video datasets: {len(video)}")
