摘要
A method for automatically updating a graphical information system (GIS) type database using aerial imagery. The method may involve processing a new image to identify at least one target region therewithin; analyzing the target region to determine image invariant moments thereof; using feature vector data to generate a template of a target feature from an old image; analyzing the template to generate image invariant moments thereof; and comparing the image invariant moments of the target region with the image invariant moments of the template to identify a feature change between the target region and the template.
