  A social behavior analysis is used to study how a group of people interacts
with another group. The analysis helps to understand how social behavior leads
to its consequences such as what business decision is made after a
businessmen's meeting. In this paper, we focus on visual human motion analysis
which is one important component of social behavior analysis. Human motion
analysis in visual surveillance usually tracks the motion of an individual or a
group of people, yet social behavior is usually neglected. This paper first
delivers a literature survey of visual surveillance, with emphasis on aspects
of human motion analysis and social behavior. Second, it offers a perspective
for social behavior analysis in an intelligent visual human monitoring system.
Third, a social interaction is induced by a social behavior between two
persons, one person and one group, or two groups, hence three general scenarios
of social interactions are outlined for future theoretical development. The
proposed human monitoring system enables the generation of valuable quantified
information of social interactions. It provides an objective approach to
evaluate performance of a human organization such as a company or a school.
Finally, it can raise the awareness of researchers to further explore the field
of social behavior analysis.
