| 摘 要： | 研究具有良好的不可察觉和稳健性能的水印算法是今后水印技术的发展方向。文中探索了一种双彩色水印算法:图像经过JPEG压缩后将比特位0置为-1,水印全部嵌入到原始载体图像的亮度分量Y中。实验证明,水印具有良好的透明性,对JPEG压缩、叠加噪声、剪切等攻击具有良好的鲁棒性。该方法易于实现,具有一定实用价值。

| Abstract: | Researching good invisible and robust watermarking algorithm is a developing direction of watermarking technique for the future.The article has groped for a bi-color watermarking algorithm: bit 0 was changed to-1 after color watermarking image has been compressed.Watermarking is embedded in luminance separation Y.Experimental results demonstrate that watermarking has good transparency and the proposed technique has good robustness to common image processing such as JPEG compression,Gaussian noise,salt & pepper noise,cropping etc. |

| Keywords: | digital watermark wavelet transform invisibility robustness |
