A New Color Image Blind Watermarking Algorithm Based on Quaternion

摘要：

In this paper, a new color image blind watermarking technology which uses the properties of the quaternion matrix is proposed. The image is represented in the form of quaternion matrix. Then many important properties of quaternion matrix singular value decomposition are discussed with several experiments to find the best field to embed the watermarking information. Fortunately, the field of QSVD transformation is very feasible to carry the watermark information. Then a blind watermarking algorithm which uses the conjugate and rotation to embed the watermarking information into the field of QSVD transformation is depicted. The experimental results indicate that the algorithm has good performance under many attacks.
