Quaternion Discrete Fourier Transform-Based Color Image Watermarking Method Using Quaternion QR Decomposition
In this paper, a new Quaternion Discrete Fourier Transform (QDFT)-based digital color image watermarking method is presented. In addition, the Quaternion QR (QQR) decomposition is applied in digital watermarking technology for the first time. First of all, the QDFT and QQR decomposition are performe...
