From videos to places: Geolocating the world’s videos

Computer Vision and Pattern Recognition (CVPR) (2011)


This paper explores the problem of large-scale automatic video geolocation. A methodology is developed to infer the location at which videos from were recorded using video content and various additional signals. Specifically, multiple binary Adaboost classifiers are trained to identify particular places based on learning decision stumps on sets of hundreds of thousands of sparse features. A one-vs-all classification strategy is then used to classify the location at which videos were recorded. Empirical validation is performed on an immense data set of 20 million labeled videos. Results demonstrate that high accuracy video geolocation is indeed possible for many videos and locations and interesting relationships exist between between videos and the places where they are recorded.
