| 摘 要： | 提出一种新的盲水印算法,通过提取原始图像的DCT域特征向量,利用两个密钥调制特征向量从而将水印信息嵌入到到数字图像中,提取水印时不需要原始图像.试验结果表明使用该算法嵌入水印的图像具有很好的图像质量,对各种程度的JPEG压缩,低通滤波,噪声干扰有很好的抵抗性.

| Abstract: | A novel blind watermarking algorithm is proposed to embed watermarking into digital images by extracting feature vectors in the DCT domain of the original images and using two keys to modulate these vectors, the watermarking are designed to be detected without the original images. Experimental results also demonstrate that this scheme can make the quality of embeded watermarking images very well and strengthen the watermarking resistance to JPEG compression, low-through filter and noise. |
