A Watermarking Scheme for Color Image Using Quaternion Discrete Fourier Transform and Tensor Decomposition

To protect the copyright of the color image, a color image watermarking scheme based on quaternion discrete Fourier transform (QDFT) and tensor decomposition (TD) is presented. Specifically, the cover image is partitioned into non-overlapping blocks, and then QDFT is performed on each image block. T...
