Description: 提出了一种离散小波变换域实现图像水印的方法。这种算法充分利用小波变换的特点,把原始图像及水印图像塔式分解,在多分辨率分解后的相同的频段来嵌入水印信息。该方法也利用了人眼视觉特性,算法简单而有效。实验证明,该算法较好地解决了水印不可见性与鲁棒性之间的矛盾,对常见的水印攻击都有较强的鲁棒性。-presents a discrete wavelet transform domain image watermarking method. This algorithm using wavelet transform characteristics, the original image and the watermark image tower decomposition, Multiresolution decomposition in the same frequency band to the embedded watermark. The method has also been used HVS, the algorithm is simple and effective. Experiments show that the algorithm can solve the watermark is visible with the robust nature of, common to have more attacks watermark robustness. Platform: |

Description: 数字水印技术是指用信号处理的方法在数字化的多媒体数据中嵌入隐蔽的标记，这种标记通常是不可见的，只有通过专用的检测器或阅读器才能提取。数字水印在信息隐藏及图象隐藏方面有着极为广泛的应用。-Digital watermarking technology is that by using the method of signal processing in the digital multimedia data embedded hidden tag, this tag is not usually visible only through a dedicated detector or reader can be extracted. Digital Watermarking and Information Hiding in the hidden image has a very wide range of applications. Platform: |

Description: Watermark A visible or invisible signature embedded inside an image to show authenticity or proof of ownership. The hidden watermark should be inseparable the host image, robust enough to resist any manipulations while preserving the image quality. Thus through watermarking, intellectual properties remains accessible while being permanently marked.-Watermark A visible or invisible signature embedded inside an image to show authenticity or proof of ownership.
