摘要:
提出一种基于图像纹理特性的数字水印算法,该算法采用分形参数描述图像纹理特征,选取粗糙纹理块作为水印的嵌入块,水印嵌入利用图像小波分解系数的塔式特性进行不同级之间相似块的替代,检测算法无需原始图像,仅需保留块嵌入位置作为密钥.由于水印算法充分利用了图像自身特点, 同时水印嵌入分块进行, 有效地提高了水印信号的鲁棒性.. .验.结果表明该方法对一般的图像处理操作具有很好的鲁棒性.
Abstract:
A digital watermarking algorithm based on image texture is proposed in this paper. The rough texture blocks of the image are chosen as host signals, which take full advantages of the image characteristics. The watermark is embedded by substituting the lower-level wavelet coefficient for the higher-level wavelet coefficient according to the tower structure of wavelet transforms. To detect the watermark, we just keep the embedding position of the watermark as a key. The robustness of the algorithm is improved because the scheme is combined with image texture characteristics and the watermark is embedded in a block manner. Experimental results show that the proposed method is robust to geometric distortions.
