Abstract

We propose two key modifications to a recent motion segmentation algorithm developed by Wang and Adelson, which greatly improve its performance. They are: (i) the adaptive k- means clustering step is replaced by a merging step, whereby the hypothesis (affine parameters of a block) which has the smallest representation error, rather than the respective cluster center is used to represent each layer, and (ii) we implement it in multiple stages, where pixels belonging to a single motion model are labeled at each stage. Performance improvement due to the proposed modifications is demonstrated on real video clips.
