Algorithm on the Basis of Visible Color Water-marking in Wavelet Water Blind-check
NI Xiao-hong · 2011
A new calculating method of visible color-marking in wavelet water blind-check mainly includes the embedment of visible water-marking,the encryption,embedment and extraction of key information and the restoration of original image.The image of the carrier and that of water-marking are both in color.An experiment of matlab6.5 has been made.It is found that this algorithm has strong robustness and transparency.
