Multiple Image Watermarking Algorithm Based on SVD
Xiao Qin · Journal of Jiangxi University of Science and Technology · 2008
Due to the fact that Multiple Image watermarking system commonly can't satisfy the need of the user's embeding the watermark independently,the paper proposes an algorithm based on CDMA spread frequency encoding which embeds the pretreated Multiple Image information in the SVD domain which is geometrically antidistorted.The algorithm can achieve multiuser embedding and distill the watermark independently.Theoretics anlysis and extensive experimental results show that this method is robust.
