Friends Meet (FM) Dataset for Group Detection and Tracking
L. Bazzani, V. Murino, and M. Cristani. Decentralized particle filter for joint individual-group tracking. CVPR2012
We present a new annotated dataset that contains groups of people that evolve, appear and disappear spontaneously, and experience split and merge events. This correspond to cocktail party-like situations in social areas where people arrive alone or with other people, move from one group to another, stay still while conversing, etc. Such a picture was missing in literature, since most of the existing datasets with labelled groups contain wlaking pedestrian with a main flow direction. We manually annotated people and groups on each frame and over time, i.e., detection and tracking of groups and individuals.
