IM2GPS: Estimating Geographic Information from a Single Image James Hays and Alexei A. Efros Carnegie Mellon University Abstract: Estimating geographic information from an image is a challenging high-level computer vision problem. The availability of vast geographically-calibrated image data has prompted computer vision to look globally. This paper proposes a simple algorithm for estimating a distribution over geographic locations from a single image using a data-driven scene matching approach. The algorithm leverages a dataset of over 6 million GPS-tagged images from the Internet. The estimated image location is represented as a probability distribution over the Earth's surface. The approach is evaluated in several geolocation tasks, showing performance up to 30 times better than chance. Geolocation estimates can support other image understanding tasks such as population density estimation, land cover estimation, and urban/rural classification. Introduction: Humans can infer location distribution from photographs, using semantic clues and data association. Computational methods are far from matching this ability, but the availability of large image collections has made data association feasible.
