Description: 由于水印为8bit的图像，所以对于置乱后的水印分辨率层G2、L1和L0，经位分解操作后都有8个位平面，嵌入函数首先计算出HL3（图2-3所示）中能嵌入G2位平面的个数，如果个数大于或等于8，则将位平面全部嵌入到HL3中；否则HL3和LH3中分别嵌入4位平面，在嵌入过程中需对位平面嵌入的位置作准确的计算。L1和L0位平面的嵌入算法与G2相同。-Since the watermark for 8bit images, so the scrambling of the watermark after the resolution of layer G2, L1 and L0, decomposition by-bit after the operation has 8 bit-plane, embedded function first calculated HL3 (as shown in Figure 2-3) in G2 can be embedded in the number of bit-plane, if the number of greater than or equal to 8, will be all embedded into the bit-plane in HL3 otherwise HL3 and LH3, respectively 4-plane embedded in the embedding process of the need for bit-plane embedded in the location of for accurate calculations. L1 and L0 embedded bitplane Algorithm and G2 the same. Platform: |

Description: 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. Platform: |

Description: 摘 要: 提出了一种基于医学图像中感兴趣区域(ROI)的盲检测水印算法, 将包含重要病理信息的灰度图像作为数字水印, 经置乱后在混沌序列的控制下嵌入到宿主小波域非感兴趣区域中。实验结果表明, 该算法在保护医学 ROI 的同时提高了水印抗 JPEG 压缩的鲁棒性, 并对篡改、 几何剪切、 滤波等均具有良好的鲁棒性和透明性, 而且混沌序列增强了系统的安全性。-Abstract: This paper presents a region of interest based on medical images (ROI) of the blind detection watermarking algorithm will contain important pathological information of gray image as digital watermark, after scrambling after the chaotic sequence embedded into the host under the control of wavelet-domain Non-interest area. The experimental results show that the algorithm in the protection of medical ROI while increasing watermark robustness against JPEG compression, and tampering, cropping, filtering Dengjun has good robustness and transparency, but also enhanced the system chaotic sequence security.
