1.
The algorithm splits the original medical image to some blocks to do integral wavelet transform,chooses four low-frequency coefficients and four high-frequency coefficients in every block,and chooses the least significant bits,then dose the XOR operations with the corresponding bit of text watermark.
该算法对原始医学图像进行分块整数小波变换,在每个分块的低频和高频分别提取4个系数,取其最低有效位与文本水印的对应位相异或,得到2个密钥作为零水印,认证时使用这2个密钥恢复水印信息。
