Motion estimation plays a key role in many video applica-
tions, such as frame-rate video conversion, video retrieval,
video surveillance, and video compression. The key issue in
these applications is to define appropriate representations
that can efficiently support motion estimation with the re-
quired accuracy. In this paper, a low-complexity object mo-
tion estimation technique is proposed that is designed to fit
the needs of high-level video representation such as in video
surveillance or retrieval applications. In these applications,
a representation of object motion in a way meaningful for
high-level interpretation, such as event detection and clas-
sification, foregoes precision of estimation. The proposed
method relies on the estimation of the displacements of the
