ORFEO Toolbox (OTB) is an open source library of image processing algorithms. OTB is based on the medical image processing library ITK and offers particular functionalities for remote sensing image processing in general and for high spatial resolution images in particular. Targeted algorithms for high resolution optical images (Pleiades, SPOT, QuickBird, WorldView, Landsat, Ikonos), hyperspectral sensors (Hyperion) or SAR (TerraSarX, ERS, Palsar) are available. Monteverdi, a satellite image viewer with access to OTB processing, will also be built as part of this script. OTB may use the following optional dependencies: opencv (use OPENCV=ON).
