Paper Abstract

Factored light-field (LF) technology helps resolving the vergence-accommodation conflict inherent to the most of conventional stereoscopic displays. The remaining challenges include decreasing computation cost of light-field factorization and improving image quality. We prototyped a dual-layer light-field stereoscope with a smartphone used as a display. We implement and compare three different methods of rank-one LF factorization and two ways of initializing them. The weighted rank-one residual iterations (WRRI) and the weighted nonnegative matrix factorization (WNMF) proved almost twice faster than Huang et al.’s method in our implementation. Our tests revealed that the best way of initialization for all the three methods is that by the square root of the LF central view values; namely, one-two iterations are enough to achieve acceptable image quality.
