| 摘 要： | 本文结合了混沌系统与小波变换实现了数字图像水印的嵌入.利用混沌系统产生的混沌序列对灰度水印图像进行调制,置乱;对待处理图像进行多级小波分解,将调制置乱后的水印按位拆分为八个二值平面,分别嵌入各层的小波系数中,从而实现水印鲁棒性和不可见性的较好结合.

| Abstract: | This paper realizes embedded watermarking which is consisted of chaotic system and wavelet transform.This method is composed of two steps.First use chaotic sequence to modulate and disorder grayed watermark.Second,decompose the image by wavelet transform,then dismantle the watermark and embed into the parameter of wavelet.So the robustness and invisibility of watermarking realized. |
