Method and device for making image cartoony and fusing image with 2D code

Abstract

The invention discloses a method and device for making an image cartoony and fusing the image with a 2D code, and relates to the technical fields of image processing and 2D codes. The method comprises that an input image is made cartoony; a standard 2D code is generated according to an input text; and the cartoony image is fused with the standard 2D code to form a cartoon 2D code. When the image is made cartoony, a Gaussian difference operator is used to describe a contour line along the tangential flow field in the edge, and double-side Gaussian smoothing and color quantification are carried out. When the image is fused with the 2D code, fusion is carried out on the basis of a module, and under the condition that content included by the 2D code is not changed, the visual display effect of the 2D code approaches a binary result of the cartoony image as possible; and fusion is carried out on the basis of image pixels. The device comprises an image cartoonlization module, a standard 2D code generation module and a cartoony 2D code fusion module. According to the invention, image cartoonlization effectively remove concrete content of the image, so that the 2D code is fused with the image in a better way, and the fused 2D code is more beautiful.

Description

technical field [0001] The invention relates to the technical fields of image processing and two-dimensional codes, in particular to a method and a device for image cartoonization and image two-dimensional code fusion. Background technique [0002] Quick response two-dimensional barcode is the most widely used two-dimensional barcode on the mobile terminal in recent years. Due to the fast recognizability of the two-dimensional code and the relatively large information storage capacity, the two-dimensional code becomes a convenient and efficient method for obtaining information. At the same time, in recent years, the widespread use of smart phones and the continuous prosperity and development of network communication technology have made people more and more accustomed to using smart phones to obtain information, which has also promoted the wide application of two-dimensional codes. However, images of QR codes are widely designed to be easily scanned and decoded and contain ...

However, how to design the QR code to be more beautiful without affecting its decoding accuracy has become a major challenge

At present, most of the methods for beautifying and personalizing QR codes are to combine a picture with QR codes to solve the problem of poor visual effect of QR codes

For the method of combining two-dimensional codes and pictures to make the two-dimensional code beautiful, sometimes the selected picture itself may not be aesthetically good, resulting in a mediocre beautification effect after being combined with the two-dimensional code
