+
+Real-time object detection, multi-object tracking, and line crossing counting for CCTV analytics applications. Upload a video to detect, track, and count objects (people, vehicles, etc.) crossing a configurable line.
+
+## Features
+
+### Detection Models
+| Model | Speed | Accuracy | Best For |
+|-------|-------|----------|----------|
+| **YOLOv8n** | Very Fast | Good | Real-time, edge devices |
+| **YOLOv8s** | Fast | Better | Balanced performance |
+| **YOLOv8m** | Medium | High | Higher accuracy needs |
+| **RT-DETR-l** | Medium | High | Dense/crowded scenes |
+
+### Tracking
+- **ByteTrack**: State-of-the-art multi-object tracking with high accuracy
+- **BoT-SORT**: Alternative tracker for comparison
+
+### Analytics
+- **Line Crossing Detection**: Count objects entering/exiting across a configurable line
+- **Per-Class Statistics**: Separate counts for each object type (person, car, truck, etc.)
+- **Movement Traces**: Visualize object trajectories over time
+
+## Use Cases
+
+### Retail Analytics
+- Customer foot traffic counting
+- Store entrance/exit monitoring
+- Peak hours analysis
+- Conversion rate calculation
+
+### Traffic Monitoring
+- Vehicle counting at intersections
+- Pedestrian flow analysis
+- Traffic pattern recognition
+
+### Security & Surveillance
+- Entrance monitoring
+- Occupancy tracking
+- Perimeter breach detection
+
+## Technical Details
+
+### Architecture
+```
+Video Input → YOLOv8/RT-DETR Detection → ByteTrack MOT → Line Crossing Counter → Annotated Output
+```
+
+### Supported Object Classes
+The system can detect and track 80 COCO classes including:
+- **People**: person
+- **Vehicles**: car, motorcycle, bus, truck, bicycle
+- **Animals**: dog, cat, horse, sheep, cow
+- And many more...
+
+### Configuration Options
+- **Detection Confidence**: Adjust sensitivity (0.1 - 0.9)
+- **IOU Threshold**: Non-max suppression threshold
+- **Track Buffer**: Frames to keep lost tracks alive
+- **Class Filter**: Focus on specific object types
+- **Line Position**: Adjustable counting line
+
+## Example Results
+
+| Scenario | Objects Tracked | Accuracy |
+|----------|-----------------|----------|
+| Retail Entrance | People | ~95% |
+| Street Traffic | Vehicles + Pedestrians | ~92% |
+| Parking Lot | Vehicles | ~94% |
