| 摘 要： | 针对目前大多数图像水印技术是关于灰度图像并且基于离散小波变换的研究,提出了一种基于整型小波变换(Integer Wavelet Transform,IWT)将彩色数字水印嵌入到彩色宿主图像中的算法。采用YCbCr色彩空间的Y分量嵌入水印,利用人类视觉系统特性(Human Visual System,HVS)实现彩色水印嵌入位置的自适应确定;彩色水印的提取不需要原始水印和原始宿主图像。实验证明,嵌入水印后的图像具有很好的不易觉察性,并且对常见的图像处理操作具有很强的鲁棒性。

| Abstract: | Most of the present image watermarking techniques are about gray image and based on Discrete Wavelet Transform (DWT).A digital watermarking algorithm for color watermark embedded to color host image based on Integer Wavelet Transform (IWT) is proposed.Encrypted watermark is embedded adaptively into the Y luminance component of the YCbCr in IWT domain according to the Human Visual System (HVS) peculiarity .The proposed algorithm allows extracting watermark without the help of original watermark and host image.Experiment results show that the proposed algorithm is invisible and robust against common image processing. |
