🎵 EmoNoteTunes

Emotion-Based Music Recommendation System

Transform your emotions into perfect music matches - Using AI to detect your feelings and recommend songs that resonate with your mood.

---

📊 Project Overview

EmoNoteTunes is an intelligent web-based application that combines computer vision and natural language processing to create personalized music recommendations based on your emotional state. By analyzing both facial expressions and text input, the system provides a sophisticated approach to music curation.

🎯 Key Statistics

• 7 Emotion Categories Supported
• 35+ Curated Songs Across All Emotions
• 2-3 Second Processing Time
• 30-40 Frames Analyzed for Accuracy
• 48x48 Pixel Face Detection Resolution
• 10 Recent Sessions Tracked

🚀 Features

🔍 Dual Emotion Detection

• 📸 Facial Emotion Recognition: Uses OpenCV and CNN models to detect emotions from webcam/uploaded images
• 📝 Text Sentiment Analysis: Leverages TextBlob for natural language sentiment processing
• 🤖 Smart Fusion: Combines both inputs for enhanced accuracy

🎼 Intelligent Music Curation

• 7 Emotion Categories: Happy, Sad, Angry, Neutral, Surprised, Fearful, Disgusted
• Personalized Recommendations: 5 songs per emotion category
• Dynamic Selection: Random sampling ensures variety in recommendations

💾 Session Management

• SQLite Database: Persistent storage of user interactions
• Session History: Track your last 10 emotion-music sessions
• Analytics Ready: Timestamp and confidence tracking

🛠️ Technical Architecture

Core Components

1. Computer Vision Pipeline

   Image Input → Face Detection → CNN Model → Emotion Classification
   

2. NLP Pipeline

   Text Input → TextBlob Analysis → Sentiment Scoring → Emotion Mapping
   

3. Recommendation Engine

   Combined Emotions → Music Database → Personalized Playlist
   

Machine Learning Models

• CNN Architecture: 3 Convolutional layers + 2 Dense layers
• Input Preprocessing: 48x48 grayscale normalization
• Confidence Scoring: Softmax activation for emotion probabilities
• Fallback System: Graceful degradation with random selection

💡 How It Works

Step-by-Step Process

1. 🖼️ Image Capture

   • Upload photo or use live webcam
   • System detects faces using Haar Cascade
   • Extracts and processes 48x48 face regions

2. 🧠 Emotion Analysis

   • CNN model predicts facial emotion (7 categories)
   • TextBlob analyzes text sentiment (-1 to +1 polarity)
   • Smart weighting combines both inputs

3. 🎵 Music Recommendation

   • Maps final emotion to music database
   • Randomly selects 5 songs from emotion category
   • Displays personalized playlist

4. 💾 Session Storage

   • Saves interaction to SQLite database
   • Tracks timestamp, emotions, and recommendations
   • Enables history viewing and analytics
