Based on the property of Ridgelet sparse representation to line singularities, a blind digital image watermarking algorithm is proposed.

利用脊波变换对直线状奇异特征的稀疏表示特性，提出了一种盲数字图像水印算法。

The experimental results demonstrate that this method can be carried out simply and has good robusticity.

最后，总结了本人的研究结果并对数字水印的进一步发展进行了展望。

Both Sime and I really like it so we decided to make it into a customized logo for my blog.

我和Sime都挺喜欢的所以觉得拿来做成水印放在博客上用。

A new digital watermarking algorithm based on spatiotemporal chaos is proposed.

本文提出一种将时空二维混沌应用到数字水印中去的算法。

This method does not require any training and can be widely used on steganography and watermark of JPEG images from various sources.

该算法无需任何的训练过程，对JPEG图像的各种数字图像隐藏和水印具有广泛的效果。

The simulation is performed by using the x-ray stomatic imaging and experimental results show that the scheme has good retrieval performance, and watermarking algorithm used in the scheme has robustness property to the JPEG compression.

运用X光口腔照片的仿真实验验证了所提出方法的有效性，所采用的数字水印算法对JPEG压缩具有良好的鲁棒性。

First, using chaotic sequences, an algorithm of embedding watermark in low frequency subband of wavelet transform image is designed.

第一，利用混沌序列的优良性能，提出了一种在小波图像低频系数中嵌入水印及检测的算法。

He can start by selecting, for example, a paperboard which is more difficult to copy because it employs the watermark technique (see TJI 2/2002) and then add other features to the pack itself, such as for instance a micro-coding system.

他可以从精选入手，比如，纸板由于其运用了水印技术（参看TJI 2/2002）在结合包装盒本身的一些其他特性像微码设计系统，会变得更难伪造。

An Integer Wavelet Transform with parameters is firstly constructed and the transmutative Rijndael code is used to construct a Hash function, and then a visible digital watermark algorithm based on the Integer Wavelet Translation with parameters, Discrete Cosine Transform and the Transmutative Rijndael encryption algorithm are presented.

构造出了带参数的整数小波，应用变型的Rijndael密码构造出了Hash函数。提出了一种基于带参数整数小波变换、离散余弦变换及变型Rijndael加密算法的可见数字水印算法。

Experimental results show that the proposed method increases embedded capacity,and has a good transparence and robustness against attacks for common image processing.

仿真实验表明，新的图像水印方法提高了嵌入的信息量，具有很好的透明性，而且对常见的图像攻击具有很强的鲁棒性。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
