PROBLEM TO BE SOLVED: To provide a location beacon database and server, method of building the location beacon database, and location based service using the same.SOLUTION: At least one vehicle is deployed including at least one scanning device having a GPS device and a Wi-Fi radio device and including a Wi-Fi antenna system. Wi-Fi signals from Wi-Fi access points are detected and identity information of the Wi-Fi access point, which was detected in conjunction with GPS location information of the vehicle, is recorded. A user device having a Wi-Fi radio device may be located. A reference database of calculated locations of Wi-Fi access points in a target area is provided. The database may be updated using newly-added position information for improving the quality of previously determined position information to avoid error-prone data.

PROBLEM TO BE SOLVED: To provide a method of representing a flexible color image. SOLUTION: The method of representing a color image includes steps of: selecting two or more colors as representative colors for a color image or a region of the color image; calculating, for each representative color, a parameter related to the color distribution in relation to each of the representative colors for the color image having the two or more representative colors or the region of the color image; calculating, for each representative color, a weight parameter that shows relative significance of the representative colors in the color image or the region of the color image, on the basis of the number of pixels corresponding to the representative colors in the color image or the region of the color image; and deriving descriptors including parameters related to the corresponding color distribution and weight parameters, for the color image or the region of the color image, using the parameter and the weight parameter.
