提出了一种基于奇异值分解鬼图(SVDGI)和盲水印算法的光学图像水印方法。首先利用SVDGI系统对水印图像进行加密，然后利用分块离散余弦变换(DCT)和整数提升小波变换(LWT)的水印算法将加密后的水印嵌入到原始图像中。该算法具有良好的不可见性和稳健性，提取水印时不需要原始宿主图像。SVDGI提供了一种新的鬼像重建方法，通过奇异值分解对测量矩阵进行修正，以更短的时间和更高的重建质量完成重建过程。测量矩阵由一个密钥组成，授权用户只有使用该密钥才能解密和重建原始水印图像。光学实验和数值模拟均验证了该方法的可行性。
An optical image watermarking method based on singular value decomposition ghost imaging (SVDGI) and a blind watermarking algorithm is proposed. The watermark image is first encrypted by an SVDGI system, then the encrypted watermark is embedded in the host image with the help of the watermark algorithm, which uses the block discrete cosine transform (DCT) and integer lifting wavelet transform (LWT). The proposed watermarking algorithm has good imperceptibility and robustness, and no original host image is needed when extracting the watermark. SVDGI provides a new reconstruction method in ghost imaging (GI) by modifying the measurement matrix with the help of singular value decomposition, which carries out the reconstruction process in less time and at higher quality. The measurement matrix composes a secret key, and only with this key can authorized users decrypt and reconstruct the original watermark image. Both optical experiments and numerical simulations validate the feasibility of the proposed method.
