Abstract
A high-definition digital color image watermark algorithm based on QR code and DWT is studied in this paper. The basic concept, theoretical framework and the application domain of the digital watermark algorithm is introduced. From the simulation results, this algorithm can achieve better universality, and can be applied to most of the color images. Watermarked digital works can achieved better quality, and the embedded watermark is difficult to be detected. In addition, the extracted two-dimensional code image can achieve a high quality, and can be scanned through the electronic equipment and the information in it can be acquired.
