Real Color Image Denoising Using t-Product- Based Weighted Tensor Nuclear Norm Minimization

IEEE Access, 2019
Color images can be seen as third-order tensors with column, row and color modes. Considering two inherent characteristics of a color image including the non-local self-similarity (NSS) and the cross-channel correlation, we extract non-local similar ...

Edge detection using nonlinear structure tensor

Nonlinear Engineering, 2022
In order to improve the performance of edge detection for noisy images, a new edge detection method based on nonlinear structure tensor is proposed. First, the tensor product of noisy images is calculated.

Tensor of Order Two and Geometric Properties of 2D Metric Space

Mathematics, 2022
A 2D metric space has a limited number of properties through which it can be described. This metric space may comprise objects such as a scalar, a vector, and a rank-2 tensor. The paper provides a comprehensive description of relations between objects in

Graded tensor products

Journal of Pure and Applied Algebra, 2009
Let \(A=A_1\oplus\cdots\oplus A_r\) be a decomposition of the associative algebra \(A\) as a direct sum of its vector subspaces \(A_i\). This decomposition is regular if for any choice of the indices \(i_j\) one has \(A_{i_1}\cdots A_{i_n}\neq 0\), and furthermore for every \(i\) and \(j\) and every \(x_i\in A_i\), \(x_j\in A_j\) one has \(x_ix_j ...

Tensor-Tensor Product Toolbox

CoRR, 2018
The tensor-tensor product (t-product) [M. E. Kilmer and C. D. Martin, 2011] is a natural generalization of matrix multiplication. Based on t-product, many operations on matrix can be extended to tensor cases, including tensor SVD, tensor spectral norm, tensor nuclear norm [C. Lu, et al., 2018] and many others.

One-Bit Function Perturbation Impact on Robust Set Stability of Boolean Networks with Disturbances

Mathematics
This paper investigates the one-bit function perturbation (OBFP) impact on the robust set stability of Boolean networks with disturbances (DBNs). Firstly, the dynamics of these networks are converted into the algebraic forms utilizing the semi-tensor ...

Tensor products and Projections

Irish Mathematical Society Bulletin, 1995
Summary: Using a conjecture of Grothendieck as focal point, we give a display of the interaction between various concepts from the geometry of Banach spaces. These concepts include tensor norms, the Banach-Mazur distance and uniformly complemented subspaces.
