摘要
为了防止彩色图像印刷行业的盗版,提出选择LAB彩色空间嵌入数字水印,且在LAB彩色空间的L分量嵌入数字水印比在B分量更合适。通过实验说明给出的彩色图像数字水印技术算法对常用的图像处理如剪切、加噪和滤波等攻击具有较好的鲁棒性、不可见性。
To prevent color image print from pirating,this paper proposes that the embedding digital watermark method could select LAB color space,and L component is more suitable than B component in LAB color space.The experiments prove that the digital watermark algorithm is invisible and robust against the original image process methods such as crop ,noise and filtering etc.
