4.5 Feature extraction

As described in the OTB Software Guide, the term Feature Extraction refers to techniques aiming at extracting added value information from images. These extracted items named features can be local statistical moments, edges, radiometric indices, morphological and textural properties. For example, such features can be used as input data for other image processing methods like Segmentation and Classification.
