An Improved Double Digital Watermarking Algorithm Based On DWT
Guoliang Zhou · Microcomputer Information · 2011
This article according to image texture feature and image processing of various wavelet graph singular value proposed one kind double digital watermarking algorithm based on SVD and DWT,which has realized disorderly extraction.The experimental result indicated that,this algorithm which has the strong robustness has realized the copyright protection and the content authentication simultaneously.
