A Data Matrix is a two-dimensional code consisting of black and white "cells" or dots arranged in either a square or rectangular pattern, also known as a matrix. The information to be encoded can be text or numeric data. Usual data size is from a few bytes up to 1556 bytes. The length of the encoded data depends on the number of cells in the ...
A matrix code or simply a 2D code, is a two-dimensional way to represent information. It can represent more data per unit area. ... Free Online Barcode Generator This ...
Rectangular Micro QR Code (also known as rMQR Code) is two-dimensional (2D) matrix barcode invented and standardized in 2022 [1] by Denso Wave as ISO/IEC 23941. [ 2 ] rMQR Code is designed as a rectangular variation of QR code and has the same parameters and applications as original QR code.
Formally, a parity check matrix H of a linear code C is a generator matrix of the dual code, C ⊥. This means that a codeword c is in C if and only if the matrix-vector product Hc ⊤ = 0 (some authors [1] would write this in an equivalent form, cH ⊤ = 0.) The rows of a parity check matrix are the coefficients of the parity check equations. [2]
The total matrix capacity for a full symbol can be calculated as (112+16*L)*L for a full Aztec code and (88+16*L)*L for a compact Aztec code, where L is the symbol size in layers. [4] As an example, the total matrix capacity of a compact Aztec code with 1 layer is 104 bits. Since code words are six bits, this gives 17 code words and two extra bits.
JAB Code (Just Another Barcode) is a colour 2D matrix symbology made of colour squares arranged in either square or rectangle grids. It was developed by Fraunhofer Institute SIT (Secure Information Technology). [1] The code contains one primary symbol and optionally multiple secondary symbols. The primary symbol contains four finder patterns ...
High Capacity Color Barcode ( HCCB) is a technology developed by Microsoft for encoding data in a 2D "barcode" using clusters of colored triangles instead of the square pixels conventionally associated with 2D barcodes or QR codes. [ 1] Data density is increased by using a palette of 4 or 8 colors for the triangles, although HCCB also permits ...
A generator matrix for a linear [,,]-code has format , where n is the length of a codeword, k is the number of information bits (the dimension of C as a vector subspace), d is the minimum distance of the code, and q is size of the finite field, that is, the number of symbols in the alphabet (thus, q = 2 indicates a binary code, etc.).
