A Trajectory Basis Selection Method for Non-Rigid Structure from Motion

Applied Mechanics and Materials (2014)

Yaming Wang Jun Zheng Ming Jiang Ying Li Xiong Wen Qing Huang

The key point of trajectory basis based Non-Rigid Structure from Motion (NRSFM) is how to tune the basis size and how to choose the best basis combination. If the basis size is too small, the trajectory is poorly represented by the basis. But too large basis size makes the system more ill-conditioned and the reconstruction error becomes unbounded. In this paper, an automatic method is proposed to select the trajectory basis, which can select appropriate basis size. The experiment results show that, compared with the empirical value from a lot of repeated experiments, the proposed method can improve both reconstruction accuracy and efficiency of NRSFM.
