Nepali Sign Language Character Dataset

This project contains a dataset of Nepali sign language characters. The dataset is organized into two categories based on the background type: Plain Background and Random Background. Each category contains subfolders representing Nepali characters, with each folder containing a specific number of images.

Folder Structure

Inside the NSL.zip the dataset is structured as follows:

├── Plain Background
│   ├── 0
│   ├── 1
│   ├── 2
│   ├── ...
│   └── 35
├── Random Background
│   ├── 0
│   ├── 1
│   ├── 2
│   ├── ...
│   └── 35

Plain Background

• Contains 36 folders labeled from 0 to 35, each representing a Nepali sign language character.
• Each folder has 1000 images of the respective character captured against a plain background.

Random Background

• Contains 36 folders labeled from 0 to 35, each representing a Nepali sign language character.
• Each folder has 500 images of the respective character captured against a random background.

Dataset Details

The dataset is designed to support machine learning and deep learning applications, particularly for tasks such as:

• Gesture recognition
• Sign language translation

Nepali Characters Mapping

Each folder number corresponds to a specific Nepali character in sign language. A mapping table or reference for these numbers should be used in conjunction with this dataset for proper labeling and interpretation.

Applications

This dataset can be utilized in:

• Training models to recognize Nepali sign language.
• Developing applications for aiding communication with the hearing-impaired community.
• Research in sign language recognition and interpretation.
