水印

To develop an effective digital media protection method, an algorithm for digital video watermarking is proposed based on binary operation in 3D wavelet transform domain.

摘要为了寻求有效的数字媒体保护方法，该文提出了一种在三维小波变换域内基于二值运算的数字视频水印嵌入算法。

One is matching and bit reversal basing on prediction arithmetic. The other is error correcting arithmetic based on digital watermark. And the paper gives relative testing result through construct a testing model.

模型中主要提出了两种纠错算法，一种是基于预测的匹配翻转算法，另一种是基于数字水印的错误检测和恢复的方法，并建立了一个测试模型，给出了相关的测试结果和分析。

They achieved reversibility via losslessly hiding the compressed version of the altered bit plane into the non-watermarked image region.

他们通过实现无损隐藏到非地区的水印图像位平面的改变压缩版本可逆性。

The blurring of security watermark is one of the important indicators in the quality inspection system of security printing.

在防伪印刷纸张质量检测系统中，纸张防伪水印的模糊是其检测的重要指标之一。

For Text Watermark, you can set different font face, font size, bold, italic or underline with different color.

对于文本水印，你可以设置不同的字体外观，字体大小，粗体，斜体或者带有不同颜色的下划线。

The experimental results show that this method has a good robustness to the popular watermark benchmarking software Checkmark.

实验结果证实对于水印基准测试软件Checkmark的各种攻击，该算法具有较强的鲁棒性。

This paper presents a Chirp typed watermarking algorithm based on information fusion.

本文提出了一种基于信息融合的Chirp类水印算法。

Create text watermark with solid color, chiseled, and three-dimensional text effect.

创建文字水印的纯色，轮廓分明，和三维文字效果。

For example, a watermark is embedded in the luminance component and a cyclically shifted version thereof in the chrominance component of a video signal.

例如，将水印嵌入在视频信号的亮度分量中，并将其循环移位版本嵌入在视频信号的色度分量中。

A receiver extracts the bit of watermark data from the selected bit position of the average value of the chrominance portion.

接收机从色度部分的平均值的选择比特位置中提取水印数据的比特。

I can not make it blossom and suits me

我不能让树为我开花

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
