| Abstract(in English) | The light ray propagation of a projector-camera system is described by Light Transport Matrix (LTM), which is often used for scene relighting, light reflection analysis, and 3D shape measurement. LTM can be estimated by using $ell_1$ minimization because LTM is sparse matrix. Alternating Direction Method of Multipliers (ADMM) is a method which can be applied to $ell_1$ minimization problem. In this paper, we speed-up ADMM by applying of Sherman-Morrison-Woodbury (SMW) for ADMM. |
