  author={Michael Ying Yang and Hanno Ackermann and Weiyao Lin and Sitong Feng and Bodo Rosenhahn},
In this paper, we propose a new framework for segmenting feature-based moving objects under affine subspace model. Since the feature trajectories in practice are highdimensional and contain a lot of noise, we firstly apply the sparse PCA to represent the original trajectories with a lowdimensional global subspace, which consists of the orthogonal sparse principal vectors. Subsequently, the local subspace separation will be achieved via automatically searching the sparse representation of the… CONTINUE READING
