This paper presents a fast algorithm to segment
moving objects in video sequences, as the first step of a fast
object tracking system. It is based on the detection of level lines
to detect closed objects contours in a scene. The detected objects
are clustered using a combination of mean shift and ensemble
clustering. The proposed method produces a temporal video
segmentation in a fraction of the processing time required by
comparable state-of-the-art particle-based methods.
