基于整数小波变换的数字图像水印实现,The proposed watermark
embedding process is realized in integer wavelet transform (IWT) domain to defend the
robustness property. Instead of inserting the watermark bits directly in the coefficients
of cover media, an indirect embedding mechanism is proposed with the reference to a
logistic map based secret key matrix which enhance the secrecy of the proposed embedding approach. Initially, the approximate sub band of the IWT transformed cover image is
selected with the intention to embed the watermark.
