```python
# Use custom segmentation model
analyzer = PhenoAI()
analyzer.segmentation_model_path = "path/to/your/custom_model.h5"

# Set custom vegetation labels
analyzer.selected_vegetation_label = "crop"  # or "grass", "tree", etc.
```

### ROI Configuration

```python
# Customize ROI generation parameters
roi_params = {
    "n_clusters": 8,        # Number of K-means clusters
    "min_roi_size": 100,    # Minimum ROI size in pixels
    "max_roi_size": 5000,   # Maximum ROI size in pixels
    "roi_shape": "polygon"  # ROI shape type
}

analyzer.set_roi_parameters(roi_params)
```

### Quality Control Thresholds

```python
# Adjust quality control parameters
quality_params = {
    "blur_threshold": 100.0,      # Laplacian variance threshold
    "brightness_min": 50,         # Minimum brightness
    "brightness_max": 200,        # Maximum brightness
    "contrast_threshold": 30      # Minimum contrast
}

## 🧪 Example Workflows

### Workflow 1: Basic Vegetation Monitoring

```python
from phenoAI import PhenoAI

# Initialize analyzer
analyzer = PhenoAI()
analyzer.input_dir = "wheat_field_2024/"

# Run complete automated workflow
results = analyzer.run_full_workflow()

# Access results
print(f"Processed {len(results['high_quality_images'])} images")
print(f"Generated {len(results['rois'])} ROIs")
print(f"GCC temporal trend: {results['vegetation_indices']['gcc_trend']}")
```

### Workflow 2: Custom ROI Analysis

```python
# Step-by-step processing with custom ROI selection
analyzer = PhenoAI()
analyzer.input_dir = "crop_monitoring/"

# Quality control
quality_results = analyzer.step1_image_quality_control()

# Vegetation segmentation
seg_results = analyzer.step2_vegetation_segmentation(quality_results)

# Generate and preview ROIs
analyzer.step3_roi_generation(seg_results)
analyzer.display_roi_preview_popup(seg_results)

# Manual ROI selection
analyzer.selected_rois = [1, 3, 5, 7, 9]  # Select specific ROIs

# Calculate indices for selected ROIs only
vi_results = analyzer.step4_vegetation_indices(roi_subset=analyzer.selected_rois)
```

### Workflow 3: Parameter Optimization

```python
# Launch GUI for parameter tuning
from phenoAI.gui import run_parameter_tuning

# Interactive parameter optimization
run_parameter_tuning()

# Apply optimized parameters
analyzer = PhenoAI()
analyzer.load_parameters("optimized_params.json")
analyzer.run_full_workflow()
```

## 🔧 Troubleshooting

### Common Issues and Solutions

#### 1. Model Loading Issues
```python
# If segmentation model fails to load
analyzer = PhenoAI()
analyzer.download_pretrained_model()  # Download latest model
analyzer.segmentation_model_path = "Model/Basic_Vegetation_Model.h5"
```

#### 2. Memory Issues with Large Datasets
```python
# Process in smaller batches
analyzer.set_batch_size(32)  # Reduce batch size
analyzer.enable_memory_optimization(True)
```

#### 3. GUI Issues
```python
# If GUI fails to launch
import tkinter as tk
try:
    root = tk.Tk()
    root.destroy()
    print("✅ Tkinter available")
except:
    print("❌ Tkinter not available - install tkinter package")
```

### Performance Optimization

```python
# Enable GPU acceleration (if available)
analyzer.enable_gpu(True)

# Parallel processing
analyzer.set_num_workers(4)  # Adjust based on CPU cores

# Memory-efficient processing
analyzer.enable_lazy_loading(True)
```
