Abstract
A new encoding scheme for motion and approximate scene segmentation in video sequences is described. The proposed segmentation partitions the scene into variable size rectangles that can be encoded efficiently in a data structure known as `a slicing floorplan tree' in VLSI design. The motion in each rectangle is represented by size parameters. We describe experiments comparing the compactness of this encoding to motion encoding in MPEG-1, and its quality to motion estimates obtained by standard computer vision techniques. These experiments establish two facts. (1) The proposed representation is flexible enough to describe motion as accurately as the output produced by the best motion algorithms developed by computer vision researchers. (2) The proposed representation is much more compact than the representation of motion in MPEG-1.
