image, labels = loader.load_image_pair("sample_001")

# Advanced processing
processor = AdvancedImageProcessor()
edges = processor.detect_edges(image, method='canny')
features = processor.extract_all_features(image)

# ML processing
ml = SatelliteMLProcessor()
buildings = ml.detect_buildings_simple(image)
ndvi = ml.extract_ndvi(image)
```
