In this paper we present a method to automatically segment a photo sequence in groups containing the same persons. Many methods in literature accomplish to this task by adopting clustering techniques. We model the problem as the search for probable associations between faces detected in subsequent photos considering the mutual exclusivity constraint: a person can not be in a photo two times, nor two faces in the same photo can be assigned to the same group. Associations have been found considering face and clothing descriptions. In particular, a two level architecture has been adopted: at the first level, associations are computed within meaningful temporal windows (situations); at the second level, the resulting clusters are re-processed to find associations across situations. Experiments confirm our technique generally outperforms clustering methods. We present an analysis of the results on a public dataset, enabling future comparison, and on private collections.
