%X 摘要： 为了对彩色图像进行版权保护和篡改定位,提出一种基于奇异值分解(singular value decomposition, SVD)和深度卷积神经网络(deep convolutional neural network, DCNN)的彩色图像多功能零水印算法。将原始RGB彩色图像转换成YCbCr彩色图像,对原始图像的Y、Cb、Cr通道离散小波变换得到的系数矩阵进行奇异值分解,得到DCNN的输入矩阵,从DCNN输出层的输入矩阵中获取原始图像信息矩阵,生成零鲁棒水印图像。从Y通道小波变换得到的低频子带系数矩阵中获取原始图像信息矩阵,生成零半脆弱水印图像。试验结果证明,提出的算法不但有效,而且对强度较大的常见攻击有较好的抵抗能力。<br>Abstract: A multipurpose zero watermarking algorithm for color image based on SVD(singular value decomposition)and DCNN(deep convolutional neural network)were proposed for the copyright protection and tamper location of color image. The original RGB color image was transformed into YCbCr color image. The Y channel, Cb channel and Cr channel were transformed by DWT(discrete wavelet transform), some matrices were got through decomposing the coefficient matrices by SVD and got the inputs matrices of DCNN. The information matrix of original image was got from the inputs matrix of output layer of DCNN and was used to generate zero robust watermarking image. The information matrix was got from the coefficient matrix of low frequency subband through the DWT of Y channel and was used to generate the zero semi-fragile watermarking image. The experimental results showed that the algorithm was not only efficient but also had good resistance to the strong common attacks
