Camera Calibration Using Gray Code
Sensors, 2019 In order to determine camera parameters, a calibration procedure involving the camera recordings of a checkerboard is usually performed. In this paper, we propose an alternative approach that uses Gray-code patterns displayed on an LCD screen.

ATTENDANCE MONITORING SYSTEM BASED ON IOT
Multitek Indonesia, 2021 Most organizations have problems manually logging one's attendance with complex methods. The process of manually signing on paper is time-consuming and unsafe. In such places it is necessary to implement an efficient attendance monitoring system.

LCD codes and LCP of codes from units of group rings
Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2019 A linear code with complementary dual(LCD) is a linear code such that LCD codes are of greatimportance due to their wide range of applications in consumer electronics,storage systems and cryptography. Group rings have a rich source of units. Alsothe well-

Matrix-Product Codes over Commutative Rings and Constructions Arising from σ,δ-Codes
Journal of Mathematics, 2021 A well-known lower bound (over finite fields and some special finite commutative rings) on the Hamming distance of a matrix-product code (MPC) is shown to remain valid over any commutative ring R.

An overview on skew constacyclic codes and their subclass of LCD codes
Advances in Mathematics of Communications, 2021 Linear complementary dual (LCD) codes were introduced by Massey in 1994 [\textit{X. Yang} and \textit{J. L. Massey}, Discrete Math. 126, No. 1--3, 391--393 (1994; Zbl 0790.94022)] and proved that asymptotically good LCD codes exists [\textit{J. L. Massey}, Discrete Math. 106/107, 337--342 (1992; Zbl 0754.94009)]. From 2016 to 2018, some authors studied

Duality of Codes Over Non-Unital Rings of Order Four
IEEE Access, 2023 In this paper, we present a basic theory of the duality of linear codes over three of the non-unital rings of order four; namely $I$ , $E$ , and $H$ as denoted in (Fine, 1993).

Explicit MDS Codes with Complementary Duals [PDF]
, 2017 In 1964, Massey introduced a class of codes with complementary duals which are called Linear Complimentary Dual (LCD for short) codes. He showed that LCD codes have applications in communication system, side-channel attack (SCA) and so on. LCD codes have

CoRR, 2017 In this paper, we investigate the rank-metric codes which are proposed by Delsarte and Gabidulin to be complementary dual codes. We point out the relationship between Delsarte complementary dual codes and Gabidulin complementary dual codes. In finite field $\mathbb{F}_{q}^{m}$, we construct two classes of Gabidulin LCD MRD codes by self-dual basis (or ...
