出了一种基于近邻插值取样法的自适应奇检测彩色图像水印算法．该算法利用近邻插值取样法，根据载体图像的
大小，自适应调节二值水印图像的尺寸，经ArnoM置乱预处理后，嵌入到彩色载体图像蓝色分量的Dcr高频系数中，检测时不需要
原载体图像．实验表明，该算法具有较强的鲁棒性和良好的不可感知性，可有效低抗剪切、加噪、锐化等常见的图像攻击．-Out of a neighbor-based interpolation of the adaptive sampling method detection singular color image watermarking algorithm. Neighbor interpolation algorithm uses the sampling method, in accordance with the size of vector images, adaptive binary watermark image of size, by scrambling ArnoM after pretreatment embedded into the color vector image of blue high-frequency component coefficient Dcr detected when do not need the original vector image. The experiments show that the algorithm has strong robustness and good can not be perceived, effectively low-shear, noise, sharpening and other common image attacks.
