We propose a novel clustering scheme for spatio-temporal
segmentation of sparse motion fields obtained from feature tracking. The
approach allows for the segmentation of meaningful motion components
in a scene, such as short- and long-term motion of single objects, groups
of objects and camera motion. The method has been developed within a
project on the analysis of low-quality archive films. We qualitatively and
quantitatively evaluate the performance and the robustness of the ap-
proach. Results show, that our method successfully segments the motion
components even in particularly noisy sequences.
