A multi-frame, region-feature based technique for motion segmentation
Yi Li, Dimitrios Hatzinakos, A.N. Venetsanopoulos · 2003
In this paper, we present an automatic, multi-frame, region-feature based motion segmentation technique. Region features are extracted from the first two frames and tracked over several frames. A few motion models are obtained by trajectory clustering on the set of trajectories of the region features' centroids. Final segmentation is obtained by region classification based on these motion models. The proposed technique combines the advantages of feature based methods and gradient based methods. Unlike the traditional two-frame formulation which is widely used in the literature, our method is a multi-frame formulation, which provides a more coherent interpretation of the scene over time and generates more reliable segmentation result.
