City name estimation by learning large image dataset using random forest
In recent years, by the spread of sharing services of images and videos, we have come to be able to acquire images and photographs of several cities in the world from the Internet. This in- formation can expect to apply to the three-dimensional model generation of the city and the frequent update of the map or scene simulation, but may cause the presentation of the wrong information when the data of various cities mingles. Therefore, we aim for the global localization of images which are taken at various cities in the world.
In the method, we introduce random forest to learn the information of each city from a street view image, then estimate the city where an inputted image taken from.
