# Evaluation Guide
|
||||
|
||||
## Overview
|
||||
|
||||
This guide covers model evaluation procedures for YOLOv8 French ID Card Detection models.
|
||||
|
||||
## 🎯 Evaluation Process
|
||||
|
||||
### 1. Basic Evaluation
|
||||
|
||||
Evaluate the best trained model:
|
||||
|
||||
```bash
|
||||
python eval.py
|
||||
```
|
||||
|
||||
This will:
|
||||
- Automatically find the best model from `runs/train/`
|
||||
- Load the test dataset
|
||||
- Run evaluation on test set
|
||||
- Save results to `runs/val/test_evaluation/`
|
||||
|
||||
### 2. Custom Evaluation
|
||||
|
||||
#### Evaluate Specific Model
|
||||
```bash
|
||||
python eval.py --model runs/train/yolov8_n_french_id_card/weights/best.pt
|
||||
```
|
||||
|
||||
#### Custom Thresholds
|
||||
```bash
|
||||
python eval.py --conf 0.3 --iou 0.5
|
||||
```
|
||||
|
||||
#### Different Model Size
|
||||
```bash
|
||||
python eval.py --model-size m
|
||||
```
|
||||
|
||||
## 📊 Evaluation Metrics
|
||||
|
||||
### Key Metrics Explained
|
||||
|
||||
1. **mAP50 (Mean Average Precision at IoU=0.5)**
|
||||
- Measures precision across different recall levels
|
||||
- IoU threshold of 0.5 (50% overlap)
|
||||
- Range: 0-1 (higher is better)
|
||||
|
||||
2. **mAP50-95 (Mean Average Precision across IoU thresholds)**
|
||||
- Average of mAP at IoU thresholds from 0.5 to 0.95
|
||||
- More comprehensive than mAP50
|
||||
- Range: 0-1 (higher is better)
|
||||
|
||||
3. **Precision**
|
||||
- Ratio of correct detections to total detections
|
||||
- Measures accuracy of positive predictions
|
||||
- Range: 0-1 (higher is better)
|
||||
|
||||
4. **Recall**
|
||||
- Ratio of correct detections to total ground truth objects
|
||||
- Measures ability to find all objects
|
||||
- Range: 0-1 (higher is better)
|
||||
|
||||
### Expected Performance
|
||||
|
||||
For French ID Card detection:
|
||||
|
||||
| Metric | Target | Good | Excellent |
|
||||
|--------|--------|------|-----------|
|
||||
| mAP50 | >0.8 | >0.9 | >0.95 |
|
||||
| mAP50-95| >0.6 | >0.8 | >0.9 |
|
||||
| Precision| >0.8 | >0.9 | >0.95 |
|
||||
| Recall | >0.8 | >0.9 | >0.95 |
|
||||
|
||||
## 📈 Understanding Results
|
||||
|
||||
### Sample Output
|
||||
|
||||
```
|
||||
Class Images Instances Box(P R mAP50 mAP50-95): 100%|██████████| 14/14
|
||||
all 212 209 1 0.99 0.995 0.992
|
||||
```
|
||||
|
||||
**Interpretation:**
|
||||
- **Images**: 212 test images
|
||||
- **Instances**: 209 ground truth objects
|
||||
- **Box(P)**: Precision = 1.0 (100% accurate detections)
|
||||
- **R**: Recall = 0.99 (99% of objects found)
|
||||
- **mAP50**: 0.995 (excellent performance)
|
||||
- **mAP50-95**: 0.992 (excellent across IoU thresholds)
|
||||
|
||||
### Confidence vs IoU Thresholds
|
||||
|
||||
#### Confidence Threshold Impact
|
||||
```bash
|
||||
# High confidence (fewer detections, higher precision)
|
||||
python eval.py --conf 0.7
|
||||
|
||||
# Low confidence (more detections, lower precision)
|
||||
python eval.py --conf 0.1
|
||||
```
|
||||
|
||||
#### IoU Threshold Impact
|
||||
```bash
|
||||
# Strict IoU (higher precision requirements)
|
||||
python eval.py --iou 0.7
|
||||
|
||||
# Lenient IoU (easier to match detections)
|
||||
python eval.py --iou 0.3
|
||||
```

|
||||
|
||||
```
|
||||
data/
|
||||
├── data.yaml # Dataset configuration
|
||||
├── train/
|
||||
│ ├── images/ # Training images
|
||||
│ └── labels/ # Training labels (YOLO format)
|
||||
├── valid/
|
||||
│ ├── images/ # Validation images
|
||||
│ └── labels/ # Validation labels
|
||||
└── test/
|
||||
├── images/ # Test images
|
||||
└── labels/ # Test labels
|
||||
```

|
||||
}
|
||||
```
|
||||
|
||||

||||
## ⚡ Performance Optimization
|
||||
|
||||
### GPU Memory Management
|
||||
|
||||
```bash
|
||||
# Reduce batch size if OOM
|
||||
python train.py --batch-size 8
|
||||
|
||||
# Use smaller image size
|
||||
python train.py --img-size 416
|
||||
|
||||
# Use smaller model
|
||||
python train.py --model-size n
|
||||
```
|
||||
|
||||
### Training Speed Optimization
|
||||
|
||||
```bash
|
||||
# Increase batch size (if memory allows)
|
||||
python train.py --batch-size 32
|
||||
|
||||
# Use larger model with more epochs
|
||||
python train.py --model-size m --epochs 300
|
||||
|
||||
# Enable mixed precision (default)
|
||||
# Already enabled in config
|
||||
```
|
||||
|
||||
## 🔧 Troubleshooting
|
||||
|
||||
### Common Training Issues
|
||||
|
||||
**1. CUDA Out of Memory**
|
||||
```bash
|
||||
# Solution: Reduce batch size
|
||||
python train.py --batch-size 8
|
||||
```
|
||||
|
||||
**2. Training Too Slow**
|
||||
```bash
|
||||
# Solution: Use smaller model
|
||||
python train.py --model-size n
|
||||
```
|
||||
|
||||
**3. Poor Accuracy**
|
||||
```bash
|
||||
# Solution: Use larger model
|
||||
python train.py --model-size m --epochs 200
|
||||
```
|
||||
|
||||
**4. Overfitting**
|
||||
```bash
|
||||
# Solution: Reduce epochs, increase patience
|
||||
python train.py --epochs 50 --patience 20
|
||||
```
|
||||
|
||||
### Debug Commands
|
||||
|
||||
```bash
|
||||
# Validate data structure
|
||||
python train.py --validate-only
|
||||
|
||||
# Check GPU availability
|
||||
python -c "import torch; print(torch.cuda.is_available())"
|
||||
|
||||
# Test with small dataset
|
||||
python train.py --epochs 5 --batch-size 4
|
||||
```
|
||||
