Description: 提出了一种基于小波域的图像数字水印算法·该算法将相互正交的两种水印(鲁棒水印和参考
水印)同时添加到经过DWT后的载体图像小波系数中,然后用小波反变换得到添加了水印的图像·用提取出
的参考水印来估计图像所受到的攻击,由于提取出的鲁棒水印所受的攻击与参考水印受到的攻击一样,因此
可以估计出原始的鲁棒水印·通过对嵌入水印的图像进行加入噪声、滤波、压缩以及裁剪等大量图像处理等试
验,均能正确检测出水印,表明该算法具有很好的感知效果和鲁棒性
-A wavelet-based image digital watermarking algorithm that the algorithm will be mutually orthogonal two watermarks (watermark robust watermarking and reference) at the same time added to the carrier after image after DWT wavelet coefficients, and then using wavelet transform has been Add a watermark image to use to extract a reference to estimate the watermark image by the attacks, as a result of the robust watermark extracted suffered attacks and the reference watermark by the same attack, it can be estimated through the original Robust Watermarking of the embedded watermark image by adding noise, filtering, compression and cutting, such as a large number of image processing such as testing, can correctly detect the watermark, show that the algorithm has good performance and robustness of perception Platform: |

Description: 图像在获取、传愉和存储过程中, 由于受多种原因如模糊、失真、噪声等的影响, 会造成图像质的下降。维纳滤波是一
种常见的图像复原方法, 该方法的思想是使复原的图像与原图像的均方误差最小原则来复原图像。但是该法其有一定的限
制性, 本文在分析维纳滤波复原图像的基础上, 针对维纳滤波复原过程中产生的振铃效应, 提出了基于维纳滤波图像复原的
改进算法。该葬法通过分析图像的边界条件, 来用对图像边界进行处理的方法, 将图像在边界处对称化。实脸结果表明, 该
方法有效地降低了维纳滤波图像复原过程中产生的振铃现象, 且复原的图像质全较好。-Wiener filtering for image restoration can be better through the establishment of motion blur this mathematical model, simulation for image restoration, while also blur the image by adding noise to recover, that must be considered when there is noise, the image signal to noise ratio , the noise autocorrelation function for image restoration Platform: |
