A Novel Trajectory Clustering Approach for Motion Segmentation

By Matthias Zeppelzauer, Maia Zaharieva, Dalibor Mitrovic, and Christian Breiteneder

Abstract

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.
