We implemented a novel vision-based system called Polymnis for the automated production of personalised video souvenirs for visitors in leisure and cultural heritage venues. Visitors are visually identiﬁed and tracked through a camera network. The system produces a personalized DVD souvenir at the end of a visitor’s stay allowing visitors to relive their experiences. Visitors are identified visitors by fusing facial and body features; then they are tracked visitors, and based on that visual information the ﬁnal product is compiled.

Sample of automatically produced video

The video is compiled by combining pre-recorded material and shots acquired online. The user is recognized by a face recognition system at her entrance. Then the cameras track the person and annotate each camera frame for her presence. Offline the content is compiled automatically to compose a video souvenir according to a rule-based system that involves director's knowledge. The visitor is able to buy the video souvenir at the exit of the entertainment park.
