Definition
Extraction of features from remotely sensed imagery is an important problem in many application domains. Current technologies for feature extraction for urban scenes rely on physical attributes as the basis for classification. Roads, railroads, rivers, buildings, center pivots, lakes, reservoirs, airports, and canals are typical examples of such features. Although this approach yields important information from imagery, low-level techniques to information extraction, classification and management limit both the analysis model and the quality and quantity of information extracted from the image. They do not yield to a higher-level analysis, which allows for a true understanding of the role that individual and groups of features play in processes akin to human cognition. The reason for their failure is the gap between the representation used for features and the models used...
