🎭 Emotion Recognition Using Face Detection 🤖

A deep learning-based project for recognizing emotions through facial expressions in real-time! This project leverages OpenCV for face detection and a trained deep learning model for emotion classification. Perfect for exploring AI applications in human emotion analysis!

🚀 Features

Real-Time Face Detection: Detect faces from a live webcam feed using OpenCV's Haar Cascade Classifier.📹
Emotion Prediction: Recognize emotions such as Happy, Sad, Angry, Neutral, and more using a trained convolutional neural network (CNN).😄 😢 😡 😐
Efficient Preprocessing: Grayscale conversion, normalization, and resizing for optimal model input.🔄
Interactive Output: Display detected faces and their predicted emotions directly on the webcam feed.💡
Flask Web App: A web interface to interact with the emotion recognition model, providing a user-friendly way to test real-time emotion detection.🌐

💻 Installation and Setup

Clone the Repository:

git clone https://github.com/yourusername/Emotion-Recognition-Using-Face-Detection.git
cd Emotion-Recognition-Using-Face-Detection

Install Dependencies:
Install the required libraries using pip:
```
pip install -r requirements.txt
```
Download Haar Cascade File: Ensure the haarcascade_frontalface_default.xml file is in the project directory. If not, download it from the [OpenCV GitHub repository] (https://github.com/opencv/opencv/tree/master/data/haarcascades).
Run the Application: Start the real-time emotion recognition script:

  python real_time_emotion.py

📊 Model Overview

The emotion recognition model is a Convolutional Neural Network (CNN) trained on a dataset of facial expressions. It processes grayscale images resized to 48x48 pixels for efficient and accurate emotion classification.

Predicted Emotions:

Happy 😊
Sad 😢
Angry 😡
Neutral 😐
Surprise 😲

Model Accuracy:

The model achieves an accuracy of 75% on the FER-2013 test dataset. While this provides a solid foundation for recognizing emotions from facial expressions, there's room for improvement. We aim to fine-tune the model for better real-world performance.

🎯 Future Enhancements

✨ Add More Emotions: Train the model to recognize additional emotions like Fear, Disgust, etc.
🔧 Improve Accuracy: Fine-tune the model for better real-world performance.
👥 Multi-Face Detection: Extend the application to predict emotions for multiple faces simultaneously.
🌐 Web Integration: Create a web-based interface for wider accessibility.

🧠 Dataset Used

The model was trained using the FER-2013 dataset, which contains labeled facial expressions.
