Automatic Cloud Detection – CNES (since 2003)

Magellium develops advanced image processing algorithms to automatically detect clouds in satellites images.

Since 2003, the French National Space Agency (CNES) has selected Magellium for a series of cloud detection technical & scientific studies. Most recently this has involved the specification and development of an operational prototype for cloud cover estimation for the Pleiades satellites using new correlation approaches between panchromatic and hyper-spectral bands.

Magellium has developed the A2NCNlib software library which includes a large collection of algorithms based on :

  • Artificial Intelligence (neural networks, SVM, fuzzy logic …),
  • Pattern recognition.
