基于全息图水印算法的研究OA
Watermarking Algorithm Based on Hologram
提出了一种频域中基于菲涅尔和傅立叶变换全息图的水印嵌入与提取算法，并从具有不同压缩比的JPEG图像中恢复水印图像，比较了两种变换下水印图像的稳定性。结果表明，该方法获得的水印图像具有较好的不可见性和稳定性，但相比较而言，基于菲涅尔全息图的水印图像稳定性效果更加理想。
Embedding and extracting algorithm for watermarking in the frequency domain based on the Fresnel and Fourier Hologram was proposed .The image watermarking was restored from the JPEG images with different compression ratios and the stability of watermarking image was compared between two different transformations .The result show that the image watermarking obtained by the proposed algorithm had perfect imperceptibility and stability .By compariso…查看全部>>
