An Authentication Code over Galois Rings with Optimal Impersonation and Substitution Probabilities
Two new systematic authentication codes based on the Gray map over a Galois ring are introduced. The first introduced code attains optimal impersonation and substitution probabilities.

The Steganography Based On Chaotic System for Random LSB Positions
The objective of hiding text in an image is hiding text without raising suspicions that the image contains a hidden message or text, which leads to protecting and maintaining text confidentiality.

Constacyclic codes over 𝔽pm[u1, u2,⋯,uk]/〈 ui2 = ui, uiuj = ujui〉
In this paper, we study linear codes over ring Rk = 𝔽pm[u1, u2,⋯,uk]/〈ui2$\begin{array}{} u^{2}_{i} \end{array} $ = ui, uiuj = ujui〉 where k ≥ 1 and 1 ≤ i, j ≤ k.

Seafood products are perceived as healthy foods. However, several species of seafood are still not fully utilized for different reasons or can be valued outside the original locale, if issues with the short shelf-life and/or the preparation/presentation ...

Gray isometries for finite $p$-groups [PDF]
We construct two classes of Gray maps, called type-I Gray map and type-II Gray map, for a finite $p$-group $G$. Type-I Gray maps are constructed based on the existence of a Gray map for a maximal subgroup $H$ of $G$.

A Gray Scale Correction Method for Side-Scan Sonar Images Based on Retinex
When side-scan sonars collect data, sonar energy attenuation, the residual of time varying gain, beam patterns, angular responses, and sonar altitude variations occur, which lead to an uneven gray level in side-scan sonar images.

Two-Dimensional Compact Variational Mode Decomposition-Based Low-Light Image Enhancement
In this paper, a novel methodology is proposed for low-light image enhancement. The proposed algorithm contains three stages: image reconstruction, image enhancement and color restoration. Two-dimensional compact variational mode decomposition (2D-TV-VMD)
