机械振动 Mechanical Vibrations, 6th Edition Signiresu Rao C++

用光流法进行运动目标检测，用opencv2实现。基于光流场分析的运动目标检测方法，不仅包含了被观察物体的运动信息，而且携带了三维结构的丰富信息，因此它不仅可以用于运动目标检测，还可以直接应用于运动目标跟踪，能够很精确的计算出运动目标的速度，同时在摄像机存在运动的情况下也能够检测出运动目标

获取键盘信息的简单测试程序，该程序说明了一些与键盘有关的事件含义以及组合键信息的获取。-keyboard access to the information simple test program, which illustrate some of the keyboard and meaning of the events and key combinations access to information.

说明：  使用STM32官方提供的DSP库进行FFT，虽然在使用上有些不灵活（因为它是基4的FFT，所以FFT的点数必须是4^n），但其执行效率确实非常高效，看图1所示的FFT运算效率测试数据便可见一斑。该数据来自STM32 DSP库使用文档(. Using the official DSP library provided by STM32 for FFT is not flexible in use (because it is the FFT of base 4, so the number of FFT points must be 4 ^ n), but its execution efficiency is really very efficient, as can be seen from the test data of FFT operation efficiency shown in Figure 1. This data comes from STM32 DSP library usage document)
