Spatio-temporal union of subspaces for multi-body non-rigid structure-from-motion

作者：

Highlights：

• We propose a joint segmentation and reconstruction framework to the challenging task of complex multi-body NRSfM by exploiting the inherent spatio-temporal union of subspace constraint.

• We propose to efficiently solve the resultant non-convex optimization problem based on the ADMM method.

• Extensive experimental results on both synthetic and real multi-body NRSfM datasets demonstrate the superior performance of our proposed framework.
