基于BEMD和位平面分解的彩色图像水印算法
TP391.41; 为了得到水印更好的鲁棒性和不可见性，以二维经验模态分解（BEMD）和位平面分解为基础，提出了一种新的彩色图像水印嵌入算法。该算法运用人类视觉系统（HVS）的特性和Arnold置乱变换，将位平面分解的水印信息嵌入到宿主图像其中一个固有模态函数（IMF）中，完成水印的有效嵌入。实验表明，该算法具有良好的鲁棒性和不可感知性，能够有效抵抗JPEG压缩、中值滤波、旋转、椒盐噪声和高斯噪声等多种恶意攻击。...

With the features of human visual system （ HVS ） and Arnold shuffling transform, it embedded the watermarking information de- composed by the bit plane into one of intrinsic mode functions（IMF） form the host image to finish the effective embedding algo- rithm. The experimental results show that the algorithm has the better robustness and imperceptibility, so it can be effective a- gainst a variety of malicious attacks such as JPEG compression, median filtering, rotating, salt and pepper noise |
