Abstract:
1. A method for determining a geographic location of a scene in a captured depiction comprising: extracting a first set of features and spatial interrelationships between the first set of features from the captured depiction by algorithmically analyzing the captured depiction; semantically classifying the first set of features to produce a semantically classified first set of features; matching the semantically classified first set of features and their corresponding spatial interrelationships against one or more second sets of semantically classified features and corresponding spatial interrelationships associated with reference depictions having known geographic locations, wherein one or more of the reference depictions represent a different perspective of the scene than the captured depiction does; when the matching is successful, identifying the geographic location of the scene in the captured depiction based on a known geographic location of a matching reference depiction from the reference depictions; and electronically representing each of the semantically classified first and second sets of features and their spatial interrelationships in corresponding concept graphs; and wherein said matching comprises comparing the concept graph representing the semantically classified first set of features and their spatial interrelationships against a set of concept graphs representing the one or more second sets of semantically classified features and their spatial interrelationships.
