| 摘 要： | 为了提高图像水印算法的鲁棒性,提出了一种分形与小波相结合的鲁棒性数字水印算法。该算法按密钥把水印信息转化为自相似分形图;对宿主图像进行离散Haar小波变换,然后将分形后的二值水印图像嵌入到Haar小波低频子带。仿真实验证明,该算法对噪声J、PEG压缩、剪切、平滑滤波等图像失真处理,均具有很好的鲁棒性。

| Abstract: | Fractal and wavelet combined robust digital watermarking algorithm was put forward to improve the robustness of image watermarking algorithm.This algorithm transformed the watermarking information into self-similar fractal image;and it discreted the host image through Haar wavelet transformation,and then embed the fractal binary watermarking image into Haar wavelet low-frequency band.The simulation experiments prove that this algorithm has good robustness to noise,JPEG compress,cutting,smoothing filtering a... |
