摘　　要：把有意义水印嵌入图像低频系数中,根据图像特征,对嵌入水印量的分布进行自适应调控,既实现了水印的盲提取,又提高了水印的不可见性和鲁棒性。The watermark with significance in the low frequency coefficients of the initial picture is inserted, according to the picture＇ s characteristics, the quantity and distribution of the watermark were inserted into the pic- ture regulating and controlling auto-adaptedly, the watermark distilling blindly is realized, at the same time, the watermark＇ s invisibility and robustness are enhanced.
