减法|国际上_背景建模技术：背景减法库（BGSLibrary）的基本框架与入口函数main()的功能

篇首语：本文由编程笔记#小编为大家整理，主要介绍了背景建模技术：背景减法库（BGS Library）的基本框架与入口函数main()的功能相关的知识，希望对你有一定的参考价值。

背景减法库&＃xff08;BGS Library &＃61; background subtraction library&＃xff09;包含了37种背景建模算法&＃xff0c;也是目前国际上关于背景建模技术研究最全也最权威的资料。本文将更加详细的介绍背景减法库&＃xff08;BGS Library&＃xff09;的基本框架与入口函数main()的功能。

BGS库的整体框架在背景建模技术&＃xff08;二&＃xff09;中已经全部给出&＃xff0c;此处从函数的角度再次给出BGS库的基本框架&＃xff0c;有利于代码的修改与维护。

如下图所示是基于C&＃43;&＃43;的BGS库的函数流程图&＃xff1a;

接下来将会对每个函数进行更加详细的分析。

首先&＃xff0c;先看入口函数main()&＃xff0c;代码如下&＃xff1a;

#include "Config.h"
#include "VideoAnalysis.h"
#include <iostream>
using namespace std;
namespace bgslibrary
class Main

private:
Main();
public:
static void start(int argc, const char **argv)

cout <<"-----------------------------------------" < cout <<"Background Subtraction Library v1.9.2 " < cout <<"http://code.google.com/p/bgslibrary " < cout <<"by: " < cout <<"Andrews Sobral (andrewssobral&＃64;gmail.com) " < cout <<"Optimized by: " < cout <<"Rui-Dong Fang(National Huaqiao University)" < cout <<"-----------------------------------------" < cout <<"Using OpenCV version " < try

int key &＃61; KEY_ESC;
do

VideoAnalysis* videoAnalysis &＃61; new VideoAnalysis;
if (videoAnalysis->setup(argc, argv)) ///videoAnalysis->setup(argc, argv)

videoAnalysis->start();
cout <<"Processing finished, enter:" < cout <<"R - Repeat" < cout <<"Q - Quit" < key &＃61; cv::waitKey();

cv::destroyAllWindows();
delete videoAnalysis;

while (key &＃61;&＃61; KEY_REPEAT);

catch (const std::exception& ex)

cout <<"std::exception:" < return;

catch (...)

cout <<"Unknow error" < return;

#ifdef WIN32
//system("pause");
#endif

;
int main(int argc, const char **argv)
bgslibrary::Main::start(argc, argv);
return 0;
