The users of Earth Observation (EO) images in all application domains require information to be focused, reliable, low cost and timely extracted, and also to be presented in a format compatible with their own needs. The EO information content extraction, particularly in the case of High Resolution satellite or airborne images, is mainly based on human expert knowledge and manual/visual interpretation. Thus, the information extraction process is too complex, too slow, too expensive and too dependent on interpreter subjectivity to be applied systematically over a large number of images.
