Constrained NMF for multiple exhibition on a single display
Temporal Psycho Visual Modulation (TPVM) was proposed recently as a new display paradigm that enables multi-exhibition on a single screen: people with different viewing devices can see independent and personalized views. Early studies have shown that TPVM can be implemented by nonnegative matrix factorization (NMF) of image sequences with additional constraints. In this paper, we introduce an algorithm that makes possible the glass-free viewing in a TPVM display system. More specifically, we design new constraints for the NMF problem and derive the solution using the block principal pivoting technique. The proposed algorithm can be readily implemented in a TPVM display system to generate the display frames. Experimental results are provided to show the effectiveness of the proposed algorithm.
