This paper presents pixel-based and region-based parametric mo-
tion segmentation methods for robust motion segmentation with the
goal of aligning motion boundaries with those of real objects in a
scene. We first describe a two-step iterative procedure for para-
metric motion segmentation by either motion-vector or motion-
compensated intensity matching. We next present a region-based
extension of this method, whereby all pixels within a predefined
spatial region are assigned the same motion label. These predefined
regions may be fixed- or variable-size blocks or arbitrary-shaped ar-
eas defined by color or texture uniformity. A particular combination
of these pixel-based and region-based methods is then proposed as a
