An analysis of the relation between visual concepts and geo-locations using geotagged images on the web
Hidetoshi Kawakubo, Keiji Yanai · 2009
Recently, a large number of geotagged images are available on photo sharing Web sites such as Flickr. In this paper, we propose image region entropy and geo-location entropy for analyzing the relation between visual concepts and geographical locations using a large-scale geotagged image database. Image region entropy represents to what extent concepts have visual characteristics, while geo-location entropy represents to what extent concepts are distributed over the world. In the experiment, we analyzed relations between image region entropy and geo-location entropy in terms of 230 nouns and 100 adjectives, and we found that the concepts with low image entropy tend to have high geo-location entropy and vice versa.
