【Special Effects】 Image_Watermarking_Method_Based_On_Multi-resolutio DL : 0: 一种基于多分辨率分解的图像水印嵌入方法【摘要】：根据小波变换的多分辨率的分析特征，提出了一种基于小波变换的水印嵌入方法，即在嵌入之前对水印做置乱处理，然后根据小波变换后的不同分辨率上的特点，将原始图像和水印进行小波分解，再将相同分辨率层次的数字水印分别嵌入其对应相同分辨率层次的原始图像中，使水印不可感知。试验结果表明，利用该方法较好的保持了图像的质量，并且对常用图像处理方法具有一定的健壮性，是一种行之有效的水印嵌入方法。-Based on multi-resolution decomposition of the image watermark embedding methods Abstract: Based on Wavelet Multi-resolution analysis of the characteristics of a wavelet-based watermark embedding method, that is, before the embedded watermark scrambling to do deal with, and then after the wavelet transform in accordance with a resolution on the different characteristics of the original image and watermark wavelet decomposition, and then the same resolution level of digital watermark embedding were the same as its corresponding original image resolution level so that the watermark can not be perceived. The experimental results show that the use of the method to maintain a good image quality, and commonly used image processing method has a certain degree of robustness, is an effective method of watermark embedding.
