Egocentric Visitors Localization in Cultural Sites
This addresses the need for visitor assistance and management analytics in cultural sites, but it is incremental as it primarily introduces a dataset.
The paper tackles the problem of localizing visitors in cultural sites using egocentric images to assist users and provide behavioral insights to managers, by collecting a large labeled dataset and showing that compelling results can be achieved with baseline experiments.
We consider the problem of localizing visitors in a cultural site from egocentric (first person) images. Localization information can be useful both to assist the user during his visit (e.g., by suggesting where to go and what to see next) and to provide behavioral information to the manager of the cultural site (e.g., how much time has been spent by visitors at a given location? What has been liked most?). To tackle the problem, we collected a large dataset of egocentric videos using two cameras: a head-mounted HoloLens device and a chest-mounted GoPro. Each frame has been labeled according to the location of the visitor and to what he was looking at. The dataset is freely available in order to encourage research in this domain. The dataset is complemented with baseline experiments performed considering a state-of-the-art method for location-based temporal segmentation of egocentric videos. Experiments show that compelling results can be achieved to extract useful information for both the visitor and the site-manager.
