Location-based Services using Image Search

Recent developments in image search has made them sufficiently efficient to be used in real-time applications. GPS has become a popular navigation tool. While GPS information provide reasonably good accuracy, they are not always present in all hand held devices nor are they accurate in all situations, for example in urban environments. We propose a system to provide location-based services using image searches without requiring GPS. The goal of this system is to assist tourists in cities with additional information using their mobile phones and built-in cameras. Based upon the result of the image search engine and database image location knowledge, the location is determined of the query image and associated data can be presented to the user.
