چکیده
This paper explores the dependence of reliable decoding of grey toned QR codes on the technical characteristics of smartphone cameras marketed in the period between 2008 and 2012. The research consisted of taking a total of 12,150 QR code pictures with different grey tones, graphic patterns and error correction codes. This research answers the question whether today’s smartphones can decode such designed QR codes. The data and instructions on the quantity and size of a certain grey tone incorporated in the QR code that are sufficient to decode the researched symbology have also been given. Graphic designers can use the results of this research to make QR codes that do not drastically reduce reliability.

Fast algorithm for decoding of systematic quadratic residue codes
A general algorithm for decoding the binary systematic quadratic residue (QR) codes with lookup tables is presented in this study. The algorithm can be applied in decoding the QR codes with either reducible or irreducible generator polynomials. If the generator polynomial of the QR codes is reducible, the number of elements in the Galois field is less than the sum of all correctable error patte...

In this paper, a modification decoding algorithm for the (89, 45, 17) QR code is proposed to decode all error patterns with weight less than six and high percentage weight-6, weight-7, and weight-8 error patterns.
متن کامل2D Barcode Image Decoding
Barcode technology is one of the most important parts of Automatic Identification and Data Capture (AIDC). Quick Response code (QR code) is one of the most popular types of two-dimensional barcodes. How to decode various QR code images efficiently and accurately is a challenge. In this paper, we revise the traditional decoding procedure by proposing a serial of carefully designed preprocessing ...
متن کاملComdined Turbo Block Decoding and Equalisation
In this paper, the combination of equalization and turbo decoding is studied. In the iterative decoding of a product code in block turbo coding system, the equalization process is performed within the iteration loop. The present study aims to investigate the decision feedback equalizer (DFE) incorporated in the iterative decoding. Simulation results show that the more severe the channel interfe...
