代码说明:

图像增强是数字图像的预处理,对图像整体或局部特征能有效地改善。为了实现对数字图像的增强处理,采用时域直方图均衡和频域高频加强滤波相结合的方法对图像进行了增强处理。利用图像中变化剧烈的信息只与高频成分有关这一原理,结合MATLAB设计实现了高频加强滤波器并对图像进行了增强处理,在此基础上使用时域直方图均衡技术再对图像进行处理。试验结果表明,两种技术的结合可以使图像的细部特征更加明显,图像更加锐化,其图像增强效果要好于单独采用其中任意一种技术的处理结果。

  • PSO优化BP神经网络模型.zip
    利用粒子群算法(PSO)对BP神经网络模型进行优化,可以对数据进行仿真训练,可以对变形监测以及其他领域的数据进行预测,实验结果表明粒子群算法(PSO)对BP神经网络模型比BP神经网络模型有着更好的预测精度以及在预测时间上也大大加快,代码是基于matlab语言自己写的。

  • PTP协议_IEEE1588_V2_中文版.zip
    【实例简介】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。
