1. IntroductionAfter hundreds of years of human settlement, each city has formed a distinct identity, distinguishing itself from other cities. In this work, we propose to characterize the identity of a city via an attribute analysis of 2 million geo-tagged images from 21 cities over 3 continents. We build a higher-level set of 7 city attributes, tailored to the form and function of cities to represent the geo-tagged images. The following is the estimated attribute distribution map, called perception map.
