Application ID: 12644328

Base Claim:
1. A method for recognizing landmark buildings shown in an input image and locating recognized landmark buildings on a map with related information, the method comprising: capturing a set of training images of one landmark building and learning a model of the landmark building from the set of training images; determining similarity scores for image pairs of different ones of said training images; clustering the training images into a set of prototypes based upon the similarity scores of said each pair of training images; storing said set of models learned for a set of landmark buildings to a storage device to build a first model database, wherein each model of one landmark building from said set of landmark buildings has a record in said database indexed by an identifier code for said landmark building, and each prototype has a record in said database linked to the record of corresponding landmark building model; capturing an input image of a candidate building; calculating the similarity score between said input image and each model stored in the model database; recognizing the building in said input image based on the largest value of the similarity scores between said input image and the models stored in the first database; locating the recognized landmark building on an electronic map; retrieving information related to the recognized landmark building from a second database operative under control of a processor circuit; and displaying the related information of the recognized landmark building on a display device to an end user.

Claim 11:
11. The method according to claim 1 wherein the step of localizing the recognized landmark building in an input image on a map with related information comprises: retrieving the location information of the landmark building from information stored in a storage device indexed by the landmark buildings, then the marking on the location of said recognized landmark building, and then retrieving for display from the information database indexed by landmark building the related information of the recognized landmark building.
