An End-to-end Method for Producing Scanning-robust Stylized QR Codes

2020

Quick Response (QR) code is one of the most worldwide used two-dimensional codes.~Traditional QR codes appear as random collections of black-and-white modules that lack visual semantics and aesthetic elements, which inspires the recent works to beautify the appearances of QR codes. However, these works adopt fixed generation algorithms and therefore can only generate QR codes with a pre-defined style. In this paper, combining the Neural Style Transfer technique, we propose a novel end-to-end method, named ArtCoder, to generate the stylized QR codes that are personalized, diverse, attractive, and scanning-robust.~To guarantee that the generated stylized QR codes are still scanning-robust, we propose a Sampling-Simulation layer, a module-based code loss, and a competition mechanism. The experimental results show that our stylized QR codes have high-quality in both the visual effect and the scanning-robustness, and they are able to support the real-world application.

Rich QR Code for Multimedia Management Applications

Lecture Notes in Computer Science, 2015

The Quick Response (QR) code is the most popular graphical code in the world today. These codes are used for storage of information, but they have a limited storage capacity. In this paper, we present a two level QR (2LQR) code, which stores information on two levels. The first (public) level is accessible to everyone and can be read by any classical QR code reader. The second (supplementary) level is readable only by a selected group of users, which have a specific reader application. This code increases storage capacity of standard QR code. We use specific textured patterns for construction of a second level. We also suggest a blind pattern recognition method, which is based on maximization of correlation values.

Message Embedded Barcode with Picturesque Representation

Two dimensional barcodes are wide used as an interface to attach potential customers and promotional material contents. However, the looks of a traditional 2nd barcode pattern is usually too obtrusive for group action into an esthetically designed promotional material. Besides, no human decipherable info is provided before the barcode is with success decoded. This paper proposes a brand new picture-embedding 2D barcode, known as PiCode, which mitigates these two limitations by mobilization a scannable 2D barcode with a picturesque look. PiCode is intended with careful concerns on each the sensory activity quality of the embedded image and therefore the decipherment lustiness of the encoded message. Comparisons with existing beautified 2nd barcodes show that PiCode achieves one among the simplest sensory activity quality for the embedded image, and maintains a more robust trade-off between image quality and decipherment lustiness in varied application conditions.

A Novel Aesthetic QR Code Algorithm Based on Hybrid Basis Vector Matrices

Symmetry, 2018

Recently, more and more research has focused on the beautification technology of QR (Quick Response) codes. In this paper, a novel algorithm based on the XOR (exclusive OR) mechanism of hybrid basis vector matrices and a background image synthetic strategy is proposed. The hybrid basis vector matrices include the reverse basis vector matrix (RBVM) and positive basis vector matrix (PBVM). Firstly, the RBVM and PBVM are obtained by the Gauss-Jordan elimination method, according to the characteristics of the RS code. Secondly, the modification of the parity area of the QR code can be applied with the XOR operation of the RBVM, and the XOR operation of the PBVM is used to change the data area of the QR code. So, the QR code can be modified to be very close to the background image without impacting the error-correction ability. Finally, in order to further decrease the difference between the QR code and the background image, a new synthesis strategy is adopted in order to obtain a better aesthetic effect. The experimental results show that it obtains a better visual effect without the sacrificing recognition rate.

Enhancing User Experience using Mobile QR-Code Application

Two-dimensional (2D) barcodes technology are becoming one of the foremost tools used in business industry precisely, in marketing strategies and business promotions, particularly using the quick response code (QR-Codes). Although, its applications are still in vague to the common man whose usage of the technology would help to ease his everyday life. This paper illustrates how the use of the QR Code technology can help to improve the experience of the users particularly in the field of retailing. The illustration featured a prototype system showing how code can be used as an alternative to the normal shopping process in some retail stores thereby easing off difficulties faced by shoppers while shopping through the use of their smartphones and at the same time providing opportunity to harness some of the potentials of both the QR code technology and their smartphones.

2D color barcodes for mobile phones

2011

We propose a new high capacity color barcode, named HCC2D (High Capacity Colored 2-Dimensional), which use colors to increase the barcode data density. The introduction and recognition of colored modules poses some new and non-trivial computer vision challenges, such as handling the color distortions introduced by the hardware equipment that realizes the Print&Scan process. We developed a prototype for generating and reading the HCC2D code format, both on desktops (Linux and Windows platforms) and on mobile phones (Android platforms). We tested this prototype in many experiments considering different operating scenarios and data densities, and compared it to known 2-dimensional barcodes.

IRJET- Two Layer QR Code with Picture Embedding

IRJET, 2020

A Quick Response code (QR code) is a two-dimensional code much the same as a barcode that encodes a message of fixed length. In this paper, we present a variation of QR code, two-layer QR code with picture embedding. It's two-layer structure can show two different messages when checked from two different directions. We propose a strategy to create such two-layer QR codes encoding two given messages in almost no time. The appearance of a conventional QR code pattern is often too obtrusive for integrating into an aesthetically designed advertisement. So we are embedding the QR code in a picture to make it's appearance good.

Decoding Different Patterns in Various Grey Tones Incorporated in the QR Code

Acta Graphica, 2016

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.
