小波变换域图像水印算法是一种对图像多尺度的空间频率分解[13]，能更好地与人类视觉系统（HVS Human Visual System）相匹配。由于小波变换具有良好的时频局部性和多分辨率表示的特点，而且，当前最新的图像压缩标准——JPEG2000 和视频的MPEG-7 压缩标准都采用了小波变换，-The wavelet transform domain image watermarking algorithm is a multi-scale image of the spatial frequency decomposition [13], to better match the human visual system (HVS Human Visual System). Because the wavelet transform has good frequency characteristics of the locality and multiresolution representation, and, the latest image compression standard- JPEG2000 and video MPEG-7 compression standards have adopted the wavelet transform,
