Sign-to-Text Translation System Using Arabic Sign Language

---

Project Overview

This project is a web application designed to translate Arabic sign language into text in real-time. It aims to bridge the communication gap between deaf and non-deaf individuals, promoting social inclusion and accessibility.

Team and Supervision

• Team Members:
• Supervisor: Dr. Ahmed Fares
• Course: Project-Based Learning (PBL)

Problem Statement

Deaf individuals face numerous challenges, including communication barriers, limited access to education and employment, social exclusion, and difficulty accessing public services. Our project addresses these issues by providing a tool that translates Arabic sign language into text, facilitating better communication and inclusion.

Project Objectives

1. Enhance Communication: Facilitate communication between sign language users and non-users.
2. Promote Inclusion: Reduce social exclusion for deaf individuals.
3. Improve Accessibility: Make communication more accessible in various settings.
4. User-Friendly: Ensure the application is easy to use across multiple devices.

Solution Overview

The web application captures real-time video and translates Arabic sign language gestures into text using a machine learning model. The solution involves several key components:

Technical Components

1. Machine Learning Model:

   • Architecture: CNN-LSTM model.
   • Framework: TensorFlow and Keras.
   • Functionality: Recognizes Arabic sign language gestures by analyzing video frames and extracting keypoints.

2. Dataset:

   • Name: KArSL dataset.
   • Content: 502 isolated sign words collected using Microsoft Kinect V2, performed by three professional signers.

3. Model Architecture:

   • Bidirectional LSTM: Captures temporal dependencies in sign language sequences.
   • Dense Layers: Classify the extracted features into 89 different sign language classes.
   • Output Layer: Uses softmax activation for classification.

4. Web Application:

   • Backend: Django (Python).
   • Frontend: HTML, CSS, JavaScript.
   • Functionality: Captures video, processes it through the machine learning model, and displays the translated text in real-time.

Results and Performance

• Accuracy: Achieved high training and test accuracies, demonstrating the effectiveness of the model.
• User Interface: Developed a user-friendly web interface to interact with the model and provide real-time translations.

Challenges and Solutions

• Uneven Frame Counts: Managed uneven frame counts in video data for consistent processing.
• Keypoint Optimization: Optimized the number of keypoints for efficient gesture recognition.

How to Use

1. Setup:

   • Clone the repository from GitHub.
   • Install required dependencies using pip install -r requirements.txt.

2. Run the Application:

   • Start the Django server using python manage.py runserver.
   • Access the web application through the provided local server address.

3. Using the Application:

   • Allow camera access for the web application.
   • Perform sign language gestures in front of the camera.
   • The application will display the translated text in real-time.

Future Work

• Expand Dataset: Include more sign language gestures and words to enhance the model’s vocabulary.
• Improve Accuracy: Refine the model to achieve even higher accuracy and reliability.
• Mobile Application: Develop a mobile version of the application for greater accessibility.

Conclusion

This project demonstrates the potential of machine learning and computer vision to create impactful solutions for real-world problems. By translating Arabic sign language into text, we aim to improve communication and inclusion for deaf individuals, making a positive difference in their lives.
