代码说明:

  以Logistic混沌映射的初值作为密钥,产生混沌序列构成加密模板来加密二值图像水印。在DCT变换域进行水印嵌入,进行非盲检测。该算法符合密码学要求,且仿真结果表明不可见性和鲁棒性良好。

  • PTP协议_IEEE1588_V2_中文版
    PTP精确时钟同步协议,IEEE 1588标准有version 1和version 2两个版本,Version 1于2002年底发布,Version 2目前最新版本为IEEE1588-2008,它提供Version 1的所有功能,并针对Version 1的不足,做出了改善。PTP协议实现时钟同步主要分为两个步骤:  1.建立同步体系,通过最佳主时钟算法,在整个同步系统中建立主从同步体系;  2.同步过程,通过交换PTP协议报文,计算并同步本地时钟。

  • 16QAM数字通信系统——MATLAB代码
    信号源产生 0、 1 等概分布的随机信号,映射到 16QAM 的星座图上,同时一路信号已经被分成了 I 路和 Q 路,后边的处理建立在这两路信号的基础上。I 路和 Q 路信号分别经过平方根升余弦 滤波器,再加入高斯白噪声,然后通过匹配滤波器(平方根升余弦滤波器) 。最后经过 采样,判决,得到 0、1 信号,同原信号进行比较,给出 16QAM 数字系统的误码。

  • pb模型转pbtxt,opencv调用
    此工程针对tensorflow自己训练的模型,pb转pbtxt,pb和pbtxt可以用opencv进行调用。大家尽量不要再下载这个文档了,积分太贵了,我无法改积分。建议大家直接把opencv更新到4.0以上,用opencv的Sample/dnn里面的脚本转换就可以了。opencv调用也建议用opencv4.0以上版本。
