Research on the Color Image Watermarking Algorithm Based on DWT-SVD Domain
Zhiming Zhang · Transactions of Shenyang Ligong University · 2006
In this paper,a hybrid watermark embedding algorithm based on DWT and SVD(singular value decomposition) is presented.The color image is used as a carrier.After decomposing the image into four matrices,the SVD is applied to each matrix,and the same watermark data are embedded to the matrix.The experiment demonstrates that this algorithm is robust to most types of attacks.
