Orfeo Toolbox

• Goals : make easier the development of new algorithms, their validation

and capitalisation, fill the gap between researchers and ORFEO users.

• CNES is responsible for design and specification.

• Open source software for Image Processing labs, users and the industry.

• Contractor : Communications et Systèmes, CS
