支持向量回归机和多小波变换在数字图像水印算法中的应用
The Application of Support Vector Regression and Multi-wavelet Transform in the Digital Image Watermarking Algorithm
【摘要】 给出一种多小波域上基于支持向量回归机的数字图像水印新算法,算法充分利用了多小波变换和支持向量回归机的优点.通过对新算法实验结果的分析和与其他算法的对比得到:算法对JPEG压缩、模糊处理、锐化等攻击具有很强的鲁棒性.
【Abstract】 This paper proposes a novel watermarking algorithm that is based on support vector regression in the multiwavelet domain.This algorithm makes good use of multiwavelet transform and support vector regression’s merits.Through the analysis on the experimental results and the other algorithm contrast are:the algorithm of JPEG compression,fuzzy processing,sharpening and other attacks has very strong robustness.
