中文摘要:
      设计了一种用于彩色印刷防伪图像的基于博奇编码的傅里叶计算全息数字水印方法。通过印刷-扫描实验,研究了扫描过程图像倾斜角度与提取的水印质量之间的关系。实验表明:该水印算法对印刷、扫描过程中的倾斜攻击等具有很好的鲁棒性,能满足彩色印刷图像的防伪要求;且倾斜角度越小( <15°),对水印质量的影响越小,倾斜角度为45°时提取的水印质量相对于其他倾斜角度下提取的水印质量略好。
英文摘要:
      A kind of Fourier hologram digital watermarking method used in color printing anti-fake image was designed based on Burch's coding method. The relation between tilt angle in scanning process and the quality of the extracted watermark was studied with printing and scanning experiment. The results showed that the watermarking algorithm has good robustness to printing and sloping attack in scanning process and can satisfy the security requirements of color printing image; the smaller of tilt angle (<15°) the smaller the impact on the quality of extracted watermark;when the tilt angle is 45°, the quality of extracted watermark is a little better than other angles.
