这是几篇在逆向工程中有可能会用到的方差计算的文章，挺不错的...

基于混合基算法的快速傅立叶变换和反变换在VDSL2中的应用与实现-Mixed-radix FFT-based fast Fourier transform and inverse transform in the application and implementation of VDSL2

利用R树，存储二维空间中的点数据，其中R树实现一个缓存的机制，使用LRU机制，使得可以快速的查找，输入查询点的坐标和要查询的k值，然后通过深度遍历算法对树进行遍历，获取查询点k个近邻点，这个设计有很大的实际用途，可以用于找到距离自己最近的某个物体等

TLD is an algorithm for tracking of unknown objects in unconstrained video streams. The object of interest is defined by a bounding box in a single frame. TLD simultaneously tracks the object, learns its appearance and detects it whenever it appears in the video. You are allowed to use TLD under the terms of the GPL version 3.0. It means that any distributed project that includes or links any portion of TLD source code has to be released with the source code under the GPL version 3.0 license or later.

概述： 目前在学院考勤系统是完全手动的凡系已采取出勤登记册上，或页。这项活动需要大量的时间和努力，和仍然是不可靠的。寄存器和页面会丢失和多个副本是很难保持。 因此必须要有一些系统可以做这种活动自动无需人工干预的。蓝牙考勤系统是一个软件，自动锁定为所有那些在类中可用的学生入学。首先它锁出勤，然后它将中的数据保存到 mysql 数据库服务器。 它的工作原理：扫描的所有蓝牙设备，然后采取从扫描设备的硬件地址。然后它从已经存储的表中提取学生信息，然后将数据存储到数据库中。
