People preserve memories of events such as birthdays, wed-dings, or vacations by capturing photos, often depicting groups of people. Invariably, some individuals in the im-age are more important than others given the context of the event. This paper analyzes the concept of the importance of individuals in group photographs. We address two spe-cific questions – Given an image, who are the most impor-tant individuals in it? Given multiple images of a person, which image depicts the person in the most important role? We introduce a measure of importance of people in images and investigate the correlation between importance and vi-sual saliency. We find that not only can we automatically predict the importance of people from purely visual cues, incorporating this predicted importance results in signifi-cant improvement in applications such as im2text (generat-ing sentences that describe images of groups of people).
