🌟 Sign Language Recognition using Deep Learning

Overview

Sign language is a crucial means of communication for individuals with hearing and speech impairments. This project aims to bridge the communication gap by developing an AI-powered Sign Language Recognition System using deep learning and computer vision. The model accurately identifies and translates sign language gestures into text or speech, enabling seamless interaction between sign language users and non-signers.

Key Features

✅ Real-time Sign Detection – Detects and translates sign language gestures in real-time. ✅ Deep Learning Powered – Utilizes CNNs (Convolutional Neural Networks) for accurate recognition. ✅ Multi-Language Support – Can be extended to recognize different sign languages (ASL, ISL, BSL, etc.). ✅ User-Friendly Interface – Interactive GUI for accessibility and ease of use. ✅ Open-Source & Expandable – Designed for scalability with future enhancements.

Tech Stack

• Programming Language: Python 🐍
• Deep Learning Framework: TensorFlow/Keras
• Computer Vision: OpenCV
• Dataset: Publicly available sign language datasets or custom dataset creation.
• Frontend: Streamlit / Flask for user interface.
• Hardware: WebCam / External Camera for gesture capture.

Project Workflow

1. Data Collection – Gather sign language images/videos from available datasets.
2. Preprocessing – Resize, normalize, and augment data for better model performance.
3. Model Training – Train a CNN-based model using TensorFlow/Keras.
4. Real-time Recognition – Deploy the trained model to detect and translate gestures.
5. GUI Integration – Build an interactive interface for real-world usability.

Installation & Setup

1. Clone the Repository:

   git clone https://github.com/yourusername/sign-language-recognition.git
   cd sign-language-recognition

2. Install Dependencies:

   pip install -r requirements.txt

3. Run the Application:

   python app.py

Dataset Used

We use the American Sign Language (ASL) dataset and self-collected gesture images. You can also fine-tune the model with custom datasets for enhanced accuracy.

Model Architecture

• Input Layer: Preprocessed sign language images
• Convolutional Layers: Extract spatial features
• Pooling Layers: Reduce dimensionality
• Fully Connected Layers: Classify gestures
• Output Layer: Softmax for sign prediction

Future Enhancements

🚀 Voice Output Integration – Convert recognized signs into speech for better communication. 🚀 Support for Multiple Sign Languages – Expand beyond ASL to global sign languages. 🚀 Mobile & Web Deployment – Extend the system to mobile applications.
