1) self-embedding watermark
自嵌入水印
1.
This paper presents a new self-embedding watermark scheme for image authentication,which extracts image features from the U component of the SVD domain to generate watermark and embeds watermark in the D component of the SVD domain.
提出了一种新颖的用于图像认证的自嵌入水印算法,在图像奇异值分解(SVD)域的U分量中提取图像特征信息生成水印,水印嵌入在SVD域的D分量中,水印的生成和嵌入都在图像本身中进行,图像认证时不需要原始图像和任何有关水印的附加信息,从而提高了水印的安全性和保密性。

self-embedding watermark technology to regard itself of vision as watermark embed watermark technology to reach vision by oneself,not only measure the ability to distort but also can repair in the area to distorting.
自嵌入水印技术是将图象本身作为水印嵌入到图象中的水印技术,不但具有检测篡改的能力,而且能够对被篡改区域进行修复。
3) watermark embedding
水印嵌入
1.
Considering the characteristic of signature image,the watermark embedding methods about binary and gray images are studied,the possible flippability lookup table of pixels in binary image is found,and the 4-level gray expression way of the signature image is found.
针对签名图像的特点,对二值图像水印嵌入方法和灰度图像水印嵌入方法进行研究,建立二值图像的像素可翻转值查找表,给出签名图像的4级灰度表示法。
2.
Every watermarking system has two main parts: watermark embedding and watermark extraction/detection.
