| 摘 要： | 提出一种基于离散小波变换的硬拷贝数字全息水印方法。首先利用共轭对称延拓傅里叶计算全息生成水印全息图;然后对其进行小波分解,将包含全部水印信息的高频分量嵌入到载体图像小波分解的中频区域以实现信息隐藏。由于全息图的频谱可控性和不可撕毁性,本文全息水印方法具有很好的不可见性,可以实现水印盲提取,不仅能够抵抗剪切、噪声、滤波和...

| Abstract: | A hardcopy digital hologram watermarking method based on discrete wavelet transform is proposed.First,the watermark was converted to a digital hologram using the computer-generated holography by the conjugate-symmetric extension.The host image and the hologram were then decomposed with discrete wavelet transform.High frequency components of the hologram were embedded into intermediate frequency components of the host image.Because of the adjustable spectrum and the tearing-resistance of the holo... |
