Query: A Survey of Visual Analysis of Human Motion and Its Applications   This paper summarizes the recent progress in human motion analysis and its
applications. In the beginning, we reviewed the motion capture systems and the
representation model of human's motion data. Next, we sketched the advanced
human motion data processing technologies, including motion data filtering,
temporal alignment, and segmentation. The following parts overview the
state-of-the-art approaches of action recognition and dynamics measuring since
these two are the most active research areas in human motion analysis. The last
part discusses some emerging applications of the human motion analysis in
healthcare, human robot interaction, security surveillance, virtual reality and
animation. The promising research topics of human motion analysis in the future
is also summarized in the last part.
