选择两张图片,一张水印图,一张嵌入图,将水印图进行Arnold置乱算法将其置乱,嵌入到嵌入图中,形成数字零水印,选用白噪声、高斯低通滤波、压缩、剪切、旋转攻击测试。以此观察图像鲁棒性(Select two pictures, a watermark and an embedded graph. We will scramble the watermark image with Arnold scrambling algorithm and embed it into the embedded map to form digital zero watermark. We choose white noise, Gauss low pass filtering, compression, shearing and rotation attack test. To observe the robustness of the image)

adaboost-algorithm
Adaboost是一种迭代算法,其核心思想是针对同一个训练集训练不同的分类器(弱分类器),然后把这些弱分类器集合起来,构成一个更强的最终分类器(强分类器)。(Adaboost is an iterative algorithm, the core idea is the same training set for different classifiers (weak classifiers), then these weak classifiers together to form a stronger final classifier (strong classifier).)
