# 🚀 **Quick Start Guide - Standalone Face Recognition**

Get your standalone face recognition application running in 5 minutes!

## ⚡ **Super Quick Start**

### **1. Install Dependencies**
```bash
pip install -r requirements_standalone.txt
```

### **2. Run the Launcher**
```bash
python launch_standalone.py
```

### **3. Choose Enhanced Version**
- Select option **2** when prompted
- The application will launch automatically

**That's it!** 🎉

## 🔧 **Manual Setup (if needed)**

### **Step 1: Check Python Version**
```bash
python --version
```
**Required**: Python 3.8 or higher

### **Step 2: Install Dependencies**
```bash
pip install opencv-python==4.8.1.78
pip install opencv-contrib-python==4.8.1.78
pip install numpy==1.24.3
pip install Pillow==10.0.0
pip install customtkinter==5.2.0
```

### **Step 3: Verify Required Files**
Ensure these files exist in your directory:
- ✅ `face_recognizer.yml` (trained model)
- ✅ `user_data.json` (user database)
- ✅ `registered_faces/` folder (face images)

### **Step 4: Launch Application**
```bash
python standalone_face_recognition_enhanced.py
```

## 🎯 **First Time Setup**

### **What You'll See**
1. **Dark-themed interface** with camera view
2. **Control buttons** on the left
3. **Information panels** on the right
4. **Camera status** at the top

### **Getting Started**
1. **Camera**: Should auto-initialize
2. **Click "Start Recognition"**: Begin face detection
3. **Position yourself**: 2-6 feet from camera
4. **Watch for green boxes**: Around detected faces
5. **Check right panel**: For recognition results

## 🎮 **Basic Controls**

| Button | Function |
|--------|----------|
| **Start Recognition** | Begin face detection and recognition |
| **Stop Recognition** | Pause the system |
| **Settings** | Adjust recognition parameters |
| **Export History** | Save results to CSV |
| **Clear History** | Remove all history entries |

## ⚙️ **Essential Settings**

### **Confidence Threshold**
- **Default**: 150
- **Lower = Stricter** recognition
- **Range**: 50-200

### **Detection Sensitivity**
- **Default**: 1.1
- **Higher = More sensitive** detection
- **Range**: 1.0-2.0

## 🔍 **Troubleshooting Quick Fixes**

### **Camera Not Working**
```bash
# Try different camera index
# Edit the line in the code:
self.cap = cv2.VideoCapture(1)  # Try 0, 1, or 2
```

### **Recognition Not Working**
- Check if `face_recognizer.yml` exists
- Verify `user_data.json` format
- Ensure face images are in `registered_faces/`

### **Poor Performance**
- Reduce detection sensitivity to 1.0
- Increase min neighbors to 7
- Check system resources

## 📱 **System Requirements**

### **Minimum**
- **OS**: Windows 10, macOS 10.14, Ubuntu 18.04
- **RAM**: 4GB
- **Camera**: USB webcam or built-in camera
- **Python**: 3.8+

### **Recommended**
- **OS**: Windows 11, macOS 12, Ubuntu 20.04
- **RAM**: 8GB+
- **Camera**: HD webcam (720p+)
- **Python**: 3.9+

## 🎯 **Pro Tips**

### **Best Results**
- **Lighting**: Bright, consistent lighting
- **Distance**: 3-4 feet from camera
- **Angle**: Face camera directly
- **Background**: Simple, uncluttered

### **Performance**
- **Close other applications** using camera
- **Good lighting** improves accuracy
- **Clean camera lens** for clarity
- **Stable internet** (if using cloud features)

## 🆘 **Need Help?**

### **Common Issues**
1. **"No module named 'cv2'"** → Install OpenCV
2. **"Camera not available"** → Check camera permissions
3. **"No trained model"** → Ensure `face_recognizer.yml` exists
4. **Poor recognition** → Adjust confidence threshold
