Personal Photo Indexing

Sorting one’s own private photo collection is a time consuming and tedious task. We demonstrate our event-centered approach to perform this task fully automatically. In the course of the demonstration, we either use our own photo collections, or invite the conference visitors to bring their own cameras and photos. We will sort the photos into a semantically meaningful hierarchy for the users within a couple of minutes. Events as a media aggregator allow a user to manage and annotate a photo collection in more convenient and natural to the human being way. Based on the recognized user behavior the application is able to re- veal the nature of an event and build its hierarchy with a event/sub-event relationship. One important prerequisite of our approach is a precise GPS based spatial annotation of the photos. To accommodate for devices without GPS chips or temporary low GPS perception, we propose an approach to enrich the collection with automatically estimated GPS data by semantically interpolating possible routes of the user. We are positive that we can provide a well received service for the conference visitors, especially since the conference venue will trigger a lot of memorable photos. Large scale experimental validation showed that the approach is able to recreate a user’s desired hierarchy with an F-measure of about 0.8.
