Photo collection contextualization

We propose a photo collection contextualization method that enriches the content of a user collection with additional photos extracted from collections of different users that attended the same event. Depending on the user needs, the selected photos may depict scenes from either the same or different aspects of the event. To achieve contextualization, we combine techniques for photo clustering to sub-events, multi-user time synchronization, and sub-event matching, utilizing visual, time and geolocation information. The proposed method has been tested on datasets provided by MediaEval 2014 SEM Task.
