Scannable image generation method fusing digital coding

Abstract

The invention discloses a scannable image generation method fusing digital coding and belongs to the field of QR code generation technology. According to the method, first, a to-be-fused image is processed based on a locally adaptive image brightness adjustment algorithm, and image colors are highlighted; second, a saliency region of the image is extracted, a weight matrix for adjusting the priority of a QR code module is obtained, and the QR code module is adjusted through Gaussian elimination; and last, the to-be-fused image with adjusted brightness and a QR code obtained after module adjustment are fused based on the weight matrix, and a final scannable QR code image is generated. The generated QR code is compatible with a coding / decoding standard of a traditional QR code, and on the premise of guaranteeing scanning robustness, the visual effect of the QR code is greatly improved, the conflict between the aesthetic sense and the robustness of the QR code is well solved, and the application scene of the QR code is expanded.

Description

technical field [0001] The invention belongs to the field of two-dimensional codes, relates to the optimization of visual effects of two-dimensional codes, in particular to a method for generating scannable images fused with digital codes. Background technique [0002] Nowadays, with the popularization of mobile phones and the rapid development of mobile Internet, QR codes, as a carrier of information, are more and more common in people's daily life, often acting as a "bridge" connecting online and offline character of. The appearance of a QR code is a graphic on a two-dimensional plane, and we call the smallest unit of a QR code a "module". Since the logic basis inside the computer is binary "0" and "1", the module of the QR code is also designed to be in two states, representing "0" or "1" respectively. The purpose of carrying information is achieved by orderly arranging different positions of different black and white modules. At the time of recognition, the QR code ca...

Problems solved by technology

These two-dimensional codes were designed to carry information at the beginning, so when designing, more attention was paid to the robustness of scanning, and the visual effect of the two-dimensional code was not considered, which brought inconvenience to the current use of two-dimensional codes: the first First, the existing QR codes are composed of disorganized black and white blocks, which do not have good visual effects and do not coordinate with the background; second, the existing QR codes do not have prompt information for the content of the QR codes

When the user scans the QR code, he cannot know what information is carried by the QR code he is scanning until the code is successfully scanned.

These two shortcomings greatly limit the enthusiasm of potential users when scanning QR codes, and affect the development and application of QR codes.
