ABSTRACT
We introduce tensor displays: a family of light field displays comprising all stacked display architectures employing light-attenuating layers illuminated by uniform or directional backlighting (i.e., any low-resolution light field emitter). Tensor displays include the capability to time-multiplex content across frames on each of the layers to improve image quality. We show that the light field emitted by an N-layer, M-frame tensor display can be represented by an Nth-order, rank-M tensor. In a related technical paper submission, we use this representation to introduce a unified optimization framework, based on nonnegative tensor factorization (NTF), encompassing all tensor display architectures (see supplementary supporting document). In this emerging technologies demonstration, we show both static, printed tensor displays, and dynamic LCD-based systems, providing wide field-of-view, bright, high-resolution, glasses-free 3D display.

Robust low tubal rank tensor completion via factor tensor norm minimization
Highlights- We give the definitions of tensor double norm and tensor Frobenius/nuclear hybrid norm, and regard them as low-rank regularization penalty of tensor ...
AbstractRecent research has demonstrated that low tubal rank recovery based on tensor has received extensive attention. In this correspondence, we define tensor double nuclear norm and tensor Frobenius/nuclear hybrid norm to induce a surrogate ...
Reshaped tensor nuclear norms for higher order tensor completion
AbstractWe investigate optimal conditions for inducing low-rankness of higher order tensors by using convex tensor norms with reshaped tensors. We propose the reshaped tensor nuclear norm as a generalized approach to reshape tensors to be regularized by ...
