Audio Content based Geotagging in Multimedia

摘要

In this paper we propose methods to extract geographically relevantinformation in a multimedia recording using its audio. Our method primarily isbased on the fact that urban acoustic environment consists of a variety ofsounds. Hence, location information can be inferred from the composition ofsound events/classes present in the audio. More specifically, we adopt matrixfactorization techniques to obtain semantic content of recording in terms ofdifferent sound classes. These semantic information are then combined toidentify the location of recording.
