Fast Watermarking Based on QR Decomposition in Wavelet Domain
سال
: 2010
چکیده: A novel blind watermarking technique based on QR decomposition in still images is proposed. The method is implemented in wavelet domain and its robustness has been evaluated against some image processing attacks and the results have been compared with two traditional methods i.e., SVD and DCT. It is shown that while the proposed scheme has low computational complexity, it has better robustness against some image processing attacks in comparison with SVD and DCT methods.
