## 🎯 Overview

The **DanceDynamics** is a production-ready web application that uses AI-powered pose detection to analyze dance movements in real-time. Built with MediaPipe, FastAPI, and modern web technologies, it provides comprehensive movement analysis with an intuitive glassmorphism user interface.

### What It Does

- 🎥 **Upload** dance videos (MP4, WebM, AVI up to 100MB)
- 🤖 **Analyze** movements using MediaPipe Pose Detection (33 keypoints)
- 🏷️ **Classify** 5 movement types (Standing, Walking, Dancing, Jumping, Crouching)
- 👤 **Track** 6 body parts with individual activity scores
- 🎵 **Detect** rhythm patterns and estimate BPM
- 📊 **Visualize** skeleton overlay on processed video
- 📥 **Download** analyzed videos with comprehensive metrics

## ✨ Key Features

### **Advanced Pose Detection**
- **33 Body Keypoints**: Full-body tracking with MediaPipe Pose
- **Real-time Processing**: 0.8-1.2x realtime processing speed
- **Confidence Scoring**: Color-coded skeleton based on detection confidence

### **Movement Classification**
- **5 Movement Types**: Standing, Walking, Dancing, Jumping, Crouching
- **Intensity Scoring**: 0-100 scale for movement intensity
- **Body Part Tracking**: Individual activity scores for head, torso, arms, legs
- **Smoothness Analysis**: Jerk-based movement quality assessment

### **Rhythm Analysis**
