  1. Use case
    1. Open a QB/Pléiades image
    2. Eventually select a ROI (rectangle on the scroll image)
    3. Run algorithm on the selected area
    4. Save result as vector data (polygons)
  2. Algorithm
    1. Multiresolution approach
      1. Radiometry only for the low resolutions (NDVI, clouds, etc.)
      2. Texture / Gabor for mid-resolution
      3. Morphological profiles for high resolution
    2. Possibility of using OpenStreetMaps as first guess
