代码说明：

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)

firefly_simple
萤火虫算法（Firefly Algorithm）是一种启发式算法，灵感来自于萤火虫闪烁的行为。萤火虫的闪光，其主要目的是作为一个信号系统，以吸引其他的萤火虫。剑桥大学的Xin-She Yang（音译：杨新社）教授提出了萤火虫算法，其假设为[1]：萤火虫不分性别，这样一个萤火虫将会吸引到所有其他的萤火虫吸引力与它们的亮度成正比，对于任何两个萤火虫，不那么明亮的萤火虫被吸引，因此移动到更亮的一个，然而，亮度又随着其距离的增加而减少如果没有比一个给定的萤火虫更亮的萤火虫，它会随机移动。亮度应与目标函数联系起来。萤火虫算法是以自然为灵感的启发式优化算法(The Firefly Algorithm (are) Algorithm is a kind of heuristic Algorithm, inspired by the behavior of the fireflies flash. Fireflies flash, its main purpose is to as a signaling system, to attract other fireflies. The university of Cambridge, Xin- She Yang (transliteration: Yang Xinshe) professor firefly algorithm is proposed, its hypothesis in [1]. Fireflies regardless of gender, such a firefly will attract all the other fireflies Attractive proportional to their brightness, for any two fireflies, less bright fireflies are attracted, so moving to a brighter, however, brightness and reduce with the increase of the distance If there is no more than a given fireflies light of fireflies, it will move randomly. Brightness should be linked with the objective function. The firefly algorithm based on natural inspiration of heuristic optimization algorithm)
