MuseumVisitors: a dataset for pedestrian and group detection, gaze estimation and behavior understanding

In this paper we describe a new dataset, under construction, acquired inside the National Museum of Bargello in Florence. It was recorded with three IP cameras at a resolution of 1280 × 800 pixels and an average framerate of five frames per second. Sequences were recorded following two scenarios. The first scenario consists of visitors watching different artworks (individuals), while the second one consists of groups of visitors watching the same artworks (groups). This dataset is specifically designed to support research on group detection, occlusion handling, tracking, re-identification and behavior analysis. In order to ease the annotation process we designed a user friendly web interface that allows to annotate: bounding boxes, occlusion area, body orientation and head gaze, group belonging, and artwork under observation. We provide a comparison with other existing datasets that have group and occlusion annotations. In order to assess the difficulties of this dataset we have also performed some tests exploiting seven representative state-of-the-art pedestrian detectors.
