What is OTB?
OTB, the ORFEO Toolbox is a library of image processing algorithms developed by CNES in the frame of the ORFEO Accompaniment Program. OTB is based on the medical image processing library ITK, http://www.itk.org, and offers particular functionalities for remote sensing image processing in general and for high spatial resolution images in particular. OTB provides: • image access: optimized read/write access for most of remote sensing image formats, meta-data access, simple visualization; • sensor geometry: sensor models, cartographic projections; • radiometry: atmospheric corrections, vegetation indices; • filtering: blurring, denoising, enhancement; • fusion: image pansharpening; • feature extraction: interest points, alignments, lines; • image segmentation: region growing, watershed, level sets; • classification: K-means, SVM, Markov random fields; • change detection. Many of these functionalities are provided by ITK and have been tested and documented for the use with remote sensing d
