Abstract

Digital photography is definitively becoming very popular due to several advantages over the analog one which include easy processing, copying, sharing and cheap storing. Moreover, storage devices for digital photos are getting cheaper and photo-capturing devices are no longer limited to digital cameras but include mobile phones, PDAs and others. As a consequence, there is a new challenge to efficiently annotate, store and retrieve these very large collections of digital photos captured. This paper addresses these issues and presents a new algorithm to help users to annotate geo-referenced photos, using user context and information from external sources. A digital library to store these photo collections and their metadata; and an experimental evaluation are also discussed.
