The motion track is an important feature to show the spatio-temporal relationship of
a video object [2, 5, 7, 8]. In this paper, we propose a novel motion track representation
to represent the motion track in the X-Y plane and the trend of velocity changes. Moreover,
a new similarity measure for comparing two motion tracks based on the representation
is proposed. Furthermore, the motion track segmentation method is proposed to
handle a complicated motion behavior and the relevance feedback is used to improve the
query results.
