<img src="MotoReID.png" alt="MotoReID" width="900">
A deep learning pipeline for **MotoGP team detection, tracking, and re-identification** from race broadcast footage. This system combines **YOLOv8** for robust object detection with **DINOv3** (Vision Transformer) embeddings for semantic team classification. It addresses specific challenges in high-speed sports computer vision: persistent identity tracking across extreme occlusions, rapid camera cuts, and motion blur. This project is in active development.

## Model Overview

This repository contains trained model weights for the [MotoReID](https://github.com/johnamit/mgp-detect) project.

### Included Weights

| File | Description | Size |
|------|-------------|------|
| `motogp_yolov8m_detector.pt` | Fine-tuned YOLOv8m for MotoGP prototype (bike) detection | ~50MB |
| `dinov3_team_classifier.pkl` | Logistic Regression classifier trained on DINOv3 embeddings | ~35KB |

## Pipeline Architecture

```
Video Frame → YOLOv8 Detector → Crop → DINOv3 Feature Extraction → Team Classifier → Re-ID Tracking
```

1. **Detection**: YOLOv8m (fine-tuned) localizes motorcycles in each frame
2. **Feature Extraction**: DINOv3 ViT-S/16 extracts dense semantic features from detected regions
3. **Classification**: Logistic Regression head predicts team identity from DINO embeddings
4. **Re-ID & Tracking**: ByteTrack + Cosine Similarity Memory Bank for persistent tracking

## Supported Teams (2025 Season)

| Manufacturer | Teams |
|--------------|-------|
| **Ducati** | Lenovo Team, Gresini Racing, VR46 Racing |
| **Aprilia** | Factory Racing, Trackhouse Racing |
| **KTM** | Factory Racing, Tech3 |
| **Honda** | Repsol HRC, LCR Honda |
| **Yamaha** | Monster Energy, Prima Pramac |

## Usage

### 1. Download Weights

```python
from huggingface_hub import hf_hub_download

# Download YOLOv8 detector
detector_path = hf_hub_download(
    repo_id="johnamit/motogp-team-detection",
    filename="motogp_yolov8m_detector.pt"
)

# Download team classifier
classifier_path = hf_hub_download(
    repo_id="johnamit/motogp-team-detection",
    filename="dinov3_team_classifier.pkl"
)
```

### 2. Prerequisites (Base Models)

These weights require the following base models:

#### YOLOv8 (Ultralytics)
```bash
pip install ultralytics
```
[YOLOv8 Documentation](https://docs.ultralytics.com/models/yolov8/)

#### DINOv3 (Meta AI)
Clone the DINOv3 repository for feature extraction:
```bash
git clone https://github.com/facebookresearch/dinov3.git
```
Download the ViT-S/16 pretrained weights from the [DINOv3 repo](https://github.com/facebookresearch/dinov3).
