# Multilingual Signature Verification Dataset

## Dataset Summary

The **Multilingual Signature Verification Dataset** is a curated collection of handwritten signatures designed for **offline signature verification** and related computer vision tasks.

The dataset contains more than **7,000 signature images** spanning three major writing systems:

- **Hindi**
- **Bengali**
- **English**

The English portion includes samples from the well-known **CEDAR Signature Dataset**, while additional Hindi and Bengali signatures have been curated to support multilingual signature verification research.

The dataset has been preprocessed and organized into ready-to-use **train**,**test** and **valid** splits for machine learning workflows.

# Supported Tasks

This dataset can be used for:

- Offline Signature Verification
- Signature Classification
- Signature Recognition
- Siamese Network Training
- Contrastive Learning
- Metric Learning
- Image Embedding Models
- Document AI Research
- Handwritten Biometrics

# Dataset Statistics

| Property | Value |
|----------|-------|
| Total Samples | 7,000+ |
| Languages | English, Hindi, Bengali |
| Data Type | Offline handwritten signatures |
| Train/Test Split | Yes |
| Image Format | PNG/JPG (depending on uploaded files) |
| Task | Signature Verification |

# Languages Included

## English

The English subset contains signatures derived from the **CEDAR Signature Dataset**, one of the most widely used benchmark datasets for offline signature verification research.

## Hindi

Contains handwritten signatures written in the Devanagari script.

## Bengali

Contains handwritten signatures written in the Bengali script.

The multilingual composition enables research on language-independent and script-independent signature verification models.
