patchwork
利用patchwork方法,嵌入0-1水印。可设置像素修改值、选择各种经典的攻击方式和控制攻击强弱。返回提取的水印信息和峰值信噪比。利用Matlab编写。(The use of patchwork approach, embedding the watermark 0-1. Modify pixel values can be set to choose a variety of classic attacks and control the strength of the attack. Back to extract the watermark information and peak signal to noise ratio. Prepared using Matlab.)

说明: 基于能量检测和周期循环检测的认知无线电频谱检测matlab代码
用周期循环检测算法检测:
首先运行a.m程序,通过此程序运算得出循环频率a值;
再运行zhouqi.m程序,对a值进行确定,通过周期循环算法对信号进行检测;
用能量检测算法检测:
运行nengliang.m检测程序,使用能量检测对信号进行检测。
检测完毕,对检测性能进行分析。
