Firstly, to ensure the security of wartermark,the wartermark image is Arnold scrambled before embedding and expanded to the twifold size of the original image.The corresponding subband data of the watermark and the red,green,blue weight for original image are combined according to the characteristic of the multiresolution decomposition of the wavelet transform.

首先亚洲日本一区二区三区在线，為保證水印的安全性色哟哟精品一区在线观看，在嵌入之前先對水印圖像作Arnold置亂處理，再將水印圖像位擴展為原始圖像的兩倍大信访廊募度蘸募丁国产97夜夜澡人人双人人人喊；然后根據(jù)小波變換的多分辨率分解特性，將位擴展水印和原始彩色圖像紅色免费国产乱伦视频、綠色96视频在线、藍色分量對應(yīng)方向上的子帶系數(shù)進行組合。

The articale makes a brief introduction of the applying background to the technology, as well as its basic characteristics. it also analyses the present typic watermark inset-algorithm and checking means, further tells some key technologies in practical application, points out a wide prospect digital video watermarking technology will certainly have.

The following question of multi-scheme and multi-watermark is mutual conflicts between district watermarkings. How to deal with the conflicts, and to analyze and stretch the capacity of the multiply data hiding technologies is the unignored problem for the research on copyright protection of MPEG-4 Audio.

多水印的應(yīng)用必然會存在相互之間的矛盾沖突以及對傳統(tǒng)的單水印模式的沖擊，如何利用網(wǎng)絡(luò)信息論青久久久国产av、通訊理論等建立合理的多水印模型來控制相互之間的矛盾沖突草草草干干干、優(yōu)化水印嵌入和檢測算法是MPEG-4音頻版權(quán)保護不容忽視的關(guān)鍵問題。

From another point of view, at first we discussed a lot of what is the real word-of-mouth marketing, I have a renminbi,"watermark" for everyone to identify if a word-of-mouth marketing is the content of the debris was to center , Then it can certainly be considered a real word-of-mouth marketing, otherwise, that is not.

從另一個角度來說亚洲色图2，大家起先討論了很多什么叫真正的口碑營銷无码三级中文字幕在线视频，那我這里有一個人民幣的&水印&可以供大家來鑒別，如果一個口碑營銷的內(nèi)容是呈碎片化的日本高清aⅴ永久免费，去中心化的人人骚人人操人人看，那它一定可以被考慮是一個真正的口碑營銷，否則，即不是黄色色播。

This is a very useful tool to watermark images in batches and with good set of features, it is totally worth.

這是一個非常有用的工具黄色你懂得，分批水印圖像具有良好的功能集，這是完全值得一区毛片视频。

Besides, extending the concept of Label-codeword and using the K-means clustering algorithm in the field of data mining for reference, we propose the algorithm of Classified Labeled Bisecting K-means clustering, based on which a robust watermark can be embedded effectively and extracted blindly.
