差分进化算法优化极限学习机程序代码(DE-ELM).zip

图像压缩的代码，使用DCT,变换，量化，熵编码。可以直接运行，运行结果很好。

在本文中，首先介绍GMSK、MSK原理，并对其产生方式进行理论分析；然后，设计了一个GMSK、MSK调制解调系统。最后，利用SIMULINK仿真分析在信道中加入高斯白噪声与不加高斯白噪声两种情况下调制波形的异同，其中还分析了各主要参数对调制的影响，同时将仿真结果与理论相比较，使研究更加深入。从而，加深对GMSK、MSK的认识和理解，为解决调制技术与移动通信技术的频谱利用率问题提供基础，对今后移动通信的研究具有积极的作用。

这个是自己用Python2.7写的基于opencv的车牌识别,目前识别率还是不怎么高,车牌定位采用的是形态学变换,分割是自己写的一个算法,识别部分采用的是kNN算法,有详细的注释!

ViBe背景建模Matlab代码实现，只完成了比较基础的部分，但与官网的实现方式差不多，速度比较快。
