Problems solved by technology

The QR code generated by this method without considering the principle of QR code encoding and decoding, in addition to achieving a mediocre beautification effect, will inevitably cause a decline in the decoding rate of the QR code, or even cause it to be undecodeable

Embodiment Construction

[0030] The embodiments of the present invention will be further described below with reference to the accompanying drawings, but the described embodiments of the present invention are illustrative rather than limiting.

[0031] A method for beautifying a QR code after fusing images, specifically comprising the following steps:

[0032] Step 1: Generate a reference QR code

[0033] Step 2: Construct the forward and reverse basis matrix

[0034] Step 3: Generate Transition QR Code

[0035] Step 4: Module attribute judgment

[0036] Step 5: Module Brightness Adjustment

[0037] The generation of the reference QR code described in step 1 is specifically implemented as follows:

[0038] 1-1. For the input background image I of size n×n, grayscale it and obtain the grayscale image I g ;

[0039] 1-2. According to the module length of the QR code, the grayscale image I g Divide into blocks according to the module structure of the original QR code, and calculate the average val...

Abstract

The invention relates to a method for beautifying QR (Quick Response) codes after fusing images. The method comprises the following steps of: binarizing an input background image to generate a reference QR code; establishing a forward basis matrix according to RS (Reed-Solomon) codes and generating a backward basis matrix through a Gauss-Jordan elimination method; carrying out black-white overturning on modules with high QR code priority by utilizing the forward and backward basis matrixes to obtain a transitional QR code image; judging attributes of the modules according to brightness adjustment of small squares in the modules; and generating a beautified QR code image through adjusting the module brightness and combining the other two channels. The method disclosed by the invention has the advantages that the transitional QR code is realized by modifying an RS data stream, so that the error correction capability of the code per se is not reduced; and meanwhile, the decoding mode of adecoder and the human visual characteristics are fit by utilizing a Gauss model to solve the block effect problem in the brightness adjustment, so that the generated QR code has a good visual effectand the decoding stability is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of QR codes, in particular to a method for beautifying a QR code after fusing images. Background technique [0002] With the advent of the Internet era and the popularization of smart phones, QR codes can be seen everywhere in daily life. At present, QR codes, as one of the entrances to the mobile Internet, have become the most Commonly used QR codes. However, the traditional QR code is composed of disorganized black and white blocks. As a communication medium, it often appears in the display area that cannot be ignored, and the poor visual effect is unsatisfactory. In view of the problems mentioned above, many methods of beautifying QR codes have been born in recent years. These methods mainly beautify the QR code by changing the color of the QR code or the shape of the module. Since the QR code will be scanned in various environments, it is often affected by ambient light, scanning angle, noise interfer...
