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: 图象增强
小波变换将一幅图象分解为大小、位置和方向都不同的分量。在做逆变换之前可以改变小波变换域中某些系数的大小，这样就能够洋选择的放大所感兴趣的分量而减小不需要的分量。
给定一个图象信号，用二维小波分析对图象进行增强处理。-Image enhancement will be a wavelet transform image decomposition for size, location and direction of the weight is different. To do before the inverse transform of wavelet transform domain can change the size of certain coefficients, so that foreigners will be able to choose to enlarge the amount of interest and reduce the unwanted weight. Given an image signal, using two-dimensional wavelet analysis of images to enhance treatment. Platform: |
