Problems solved by technology

There are also some businesses that ask designers to design QR codes with a strong sense of effect, but because the design specifications do not conform to the coding logic of the QR code itself, it is difficult to recognize highly personalized QR codes
[0004] The existing technology is to use simple beautification rules to fuse the two-dimensional code of the picture, and the generated composite picture has a bad aesthetic effect and may not be correctly recognized

Abstract

The present invention relates to a two-dimensional code-based image processing method, a two-dimensional code-based image processing device and a two-dimensional code. The method includes the following steps that: original information is encoded according to a two-dimensional code encoding algorithm, so that a two-dimensional code can be generated; a two-dimensional code mask is generated according to the two-dimensional code; a halftone image is generated through adopting a halftone image generating method based on the target image; and the two-dimensional code mask and the halftone image are fused through using a PCA (principal component analysis) method, so that a composite image can be generated. An effect picture obtained after the fusion of a two-dimensional code generated by the image processing method and a personalized picture can meet a requirement for scanning clarity, and the feature information of the two-dimensional code and the personalized picture can be reserved as much as possible.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, in particular, to an image processing method and device based on a two-dimensional code, and a two-dimensional code. Background technique [0002] With the popularity of WeChat, Alipay and other application programs (APP), QR codes have become an indispensable part of life. [0003] In order to tap a larger market, merchants have launched personalized QR codes that catch people's attention. However, at present, the degree of personalization of QR codes is still relatively limited, mainly by changing the color of the QR code itself, or embedding a small merchant logo in the middle of the QR code. Some businesses also ask designers to design QR codes with a strong sense of effect, but because the design specifications do not conform to the coding logic of the QR code itself, it is difficult to recognize highly personalized QR codes. [0004] The existing technology uses simple b...
