数字水印广泛应用于所有权认证和版权保护。本文提出了一种有效的阈值化方法来改进图像水印的嵌入过程。对于该算法，水印在图像的每一个块中分别进行，并在每一个块中继续嵌入，直到达到一定的结构相似度阈值。数值计算结果表明，在水印容量不变的情况下，该方案提高了水印的不可感知性，同时保证了抗攻击的鲁棒性。该方法适用于大多数图像水印算法。我们在离散余弦变换(DCT)、小波和空域的水印方案中验证了这个问题。

英文摘要：
Digital watermarking is extensively used in ownership authentication and copyright protection. In this paper, we propose an efficient thresholding scheme to improve the watermark embedding procedure in an image. For the proposed algorithm, watermark casting is performed separately in each block of an image, and embedding in each block continues until a certain structural similarity threshold is reached. Numerical evaluations demonstrate that our scheme improves the imperceptibility of the watermark when the capacity remains fix, and at the same time, robustness against attacks is assured. The proposed method is applicable to most image watermarking algorithms. We verify this issue on watermarking schemes in Discrete Cosine Transform (DCT), wavelet, and spatial domain.
