查询词典 watermark

Then the digital audio signal is set into segments and DWT is performed. Finally the modulated signal is embedded in the coefficients with relatively large absolute value on middle frequency range detail signal adaptively. The original digital audio signal is necessary when detecting the watermark.

在应用扩频技术的算法中，首先将视觉上可辨的二值水印图像降维为一维序列，再将一维水印序列伪随机排序并与m序列作扩频调制，最后对数字音频信号进行分段离散小波变换，把经过调制的水印信息自适应地嵌入到原音频信号小波分解中等尺度绝对值较大的分量上。

The success that a lot of people say a website is to rely on hard to mix assiduous, I am not denied but the operation that succeeds when us after a website the cost that comes again from the beginning is too big we can use us completely already some websites will do some of relevant couplet, I apply this successful website to because I am main,found my other website namely is to make picture website, what so one my website makes example conclude result website is duplicate, my advocate the picture of the station is to contain a bit make picture website experience friend of watermark to know the picture takes watermark to collect value basically with respect to it doesn't matter so this website basically is affirmation is improper for the friend that invites nudnik to look to want to collect to those, it is enough that every month earns bit of pocket money also be those websites that do not have profit pattern another going law I think consistently stationmaster should not waiting for the sky to drop gold to rely on advertisement is a leg walk either long plan besides current.

很多人都说网站的成功是靠努力和勤奋，我不否认但当我们成功的运营了一个网站后呢从头再来的代价太大了我们完全可以利用我们已有的网站来做些相关联的，我就是运用这个成功的网站来创建我的其他网站因为我主要是作图片网站，所以一我的网站作例子来谈成功网站的复制，我的主站的图片都是带有水印的有一点作图片网站经验的朋友都知道图片带水印基本就没什么收藏价值了所以这个网站主要是让无聊的人看看对于那些想要收藏的朋友来说肯定不合适于是我就做了第二个网站-论坛搞些杂图再把那些整站的套图打包出售这样的盈利模式是成功的论坛的vip会员现在已经达到150人左右带上广告和下载，每个月赚点零用钱是足够的也是那些没有盈利模式的网站的别样走法我一致认为站长不应该等着天上掉金子靠广告是一条腿走路不是长久之计再说了现在的广告联盟越来越垃圾也赚不到钱我们应该两手都要抓两手都要硬。
