Abstract:

In order to improve the recognition and diversity of quick response (QR) Code, this paper analyzes Halftone algorithm, illustrates its basic idea, advantages and disadvantages, and extends Halfton. In addition, based on some ideas from Halftone and QArt, a new artistic algorithm called Half-Art is put forward. The algorithm is divided into two stages: data modifcation and image processing. The mathematical features of the ReedSolomon codes (RS codes) and binarized layer masking algorithm are used to combine the target image with the QR Code. The algorithm combines the advantages, makes up shortcomings of Halftone and QArt. The optimized QR Code has good readability when spread through electronic channels.

Key words: QR Code, extended Halftone, artistic, Half-Art
