Color Image Restoration Using Sub-Image Based Low-Rank Tensor Completion [PDF]

open access: yesSensors, 2023
Many restoration methods use the low-rank constraint of high-dimensional image signals to recover corrupted images. These signals are usually represented by tensors, which can maintain their inherent relevance.

Completely Positive Binary Tensors [PDF]

open access: yesMathematics of Operations Research, 2019
A symmetric tensor is completely positive (CP) if it is a sum of tensor powers of nonnegative vectors. This paper characterizes completely positive binary tensors. We show that a binary tensor is completely positive if and only if it satisfies two linear matrix inequalities.

Spectral Algorithms for Tensor Completion [PDF]

open access: yesCommunications on Pure and Applied Mathematics, 2018
In the tensor completion problem, one seeks to estimate a low‐rank tensor based on a random sample of revealed entries. In terms of the required sample size, earlier work revealed a large gap between estimation with unbounded computational resources (using, for instance, tensor nuclear norm minimization) and polynomial‐time algorithms. Among the latter,

A parallel multi‐block alternating direction method of multipliers for tensor completion

open access: yesIET Image Processing, 2021
This paper proposes an algorithm for the tensor completion problem of estimating multi‐linear data under the limitation of observation rate. Many tensor completion methods are based on nuclear norm minimization, they may fail to achieve the global ...
