Abstract

People preserve memories of events such as birthdays, weddings,
or vacations by capturing photos, often depicting
groups of people. Invariably, some individuals in the image
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 specific
questions – Given an image, who are the most important
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 visual
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 (generating
sentences that describe images of groups of people).
