摘要:In order to improve the robustness and imperceptibleness of the algorithm, a new embedding and
extracting method with DWT-SVD is proposed. The approximation matrix of the third level of image in DWT domain
is modified with SVD to embed the singular value of watermark to the singular value of DWT coefficient. The
proposed embedding and extracting method was employed to accelerate the hybrid DWT-SVD watermarking and to
avoid the leak of watermark. This hybrid technique leads to optimize both the fundamentally conflicting requirements.
The experimental results show both the good robustness under numerous attacks and the high fidelity. The time needed
to perform the program is greatly decreased.
