A robust image - adaptive public watermarking algorithm based on dwt and blocks classification 基于小波域和块分类的鲁棒自适应水印算法
We analysis the features of color image , choose the area in which watermarking is to be embedded , improve the classify of image blocks on hvs 研究了彩色图像特点,根据dct特点确定了水印嵌入区域,在原有的hvs图像块分类的基础上进行改进,完善了hvs图像块分类。
Based on the result of classification , watermark components with different strength are inserted into different wavelet coefficients . the experimental results show that the watermarks generated with the proposed algorithm are invisible and robust against noise and commonly used image processing techniques . 8 该算法利用我们设计的分类器将小波块分类,并利用hvs的掩蔽特性实现水印分量的自适应嵌入,所实现的隐形水印对常见的图象处理和噪声干扰具有很好的稳健性。
