🧠 Talking Hands – Real-Time Sign Language Detection ✋🤟

Welcome to Talking Hands, a real-time sign language detection system built to interpret American Sign Language (ASL) gestures using computer vision and deep learning.

🚀 Project Overview

Talking Hands uses webcam video to detect hand gestures and classify them into ASL numbers (0–9). The goal is to bridge communication gaps and make gesture-based interactions more accessible using AI.

🎯 Key Features

• 🔎 Real-time hand gesture recognition
• 🤖 CNN-based model trained on ASL digit images
• 🧠 MediaPipe & OpenCV for hand tracking and image preprocessing
• 💻 Webcam-based live predictions
• 📊 Visual output with gesture overlay and predicted digit

🛠️ Tech Stack

Tool/Library	Purpose
Python	Main programming language
OpenCV	Video capture and preprocessing
MediaPipe	Hand tracking and landmarks
TensorFlow/Keras	Model training and inference
NumPy/Pandas	Data handling and manipulation
Matplotlib	Model evaluation and visualization

🖼️ Model Architecture

• Convolutional Neural Network (CNN) trained on ASL digit dataset (0–9)
• Input: Processed hand images from webcam
• Output: Digit class (0–9)

🧪 How to Run

1. Clone the repo

   git clone https://github.com/gurpreetgitsingh13/Sign-Language-Detection---Talking-Hands.git
   cd Sign-Language-Detection---Talking-Hands

2. Install dependencies

   pip install -r requirements.txt

3. Run the detection script

   python src/predict.py

4. Make hand gestures (0–9) in front of your webcam and see predictions in real-time!
