水印

First, a transformation of the model to an affine invariant space was finished prior to watermark embedding.

提出了一种基于3D网格物体的鲁棒性盲水印方案。

In affine invariant space, the 3D object is not affected by geometric transformations, such as translation, rotation and scaling.

由于在仿射不变空间下，3D物体模型不受平移、旋转和比例变换的影响，故该水印方案对于此类变化具有很强的鲁棒性。

In this paper,a blind image watermarking algorithm robust against affine transformation is proposed.

本文提出了一个抗仿射变换攻击的图像水印盲检测算法。

Experimental results show that this algorithm has obvious low complexity, high watermark payload and the strong robustness against compression, re- compression, antinoise and mean frames.

实验结果证明该算法具有低计算复杂度和大容量水印承载能力，并具有很强的抗压缩、多次压缩、抗噪声的能力。

In the main application window, you can select the position of watermark on the image.

在主要的应用程序窗口，你可以选择的立场，水印的图片。

This paper introduces characteristics, priple, model of watermark. At the same time, some classical arithmetics are expatiated in it.

本文从数字水印技术本身的特点、一般模型和典型算法出发，介绍了一种可以快速上手的高效的实用语言－Matlab。

The scheme is based on non-mean quantisation parameters with invariant features,it utilises the concept of the 2-nd generation digital watermarking and uses the technique of quantisation watermarking.

针对商品包装图像在水印检测过程中图像会发生变形的问题展开研究，提出一种基于非均值量化系数特征不变的盲数字水印方案。

In this paper,we present a hybrid watermark embedding scheme base on DWT and Singular Value Decomposition.

数字水印是多媒体数字产品版权保护的重要技术之一，目前许多关于图像融合的研究都在空域中进行，隐藏水印图像抗攻击的能力较差。

Watermark: A design pressed into the wet paper during papermaking by the dandy roll to indicate quality and provide a means to guard against counterfeit in case of security printing.

水印：在造纸时，由水印辘在湿纸卷上压上，表示品质的图形。它在保密印刷方面，提供一个防止假冒的方法。
