This repository is the C++ Source Code of several algorithms of Extracting Background, which are based on OpenCV libraries after I learn about the theory of these algorithms(including Frame-Difference, Gauss-Background-Difference, ViBe algorithms).

This repository is the C++ Source Code of several algorithms of Extracting Background, which are based on OpenCV libraries after I learn about the theory of these algorithms. These Extracting Background Algorithms includes Frame-Difference Algorithm, Gauss-Background-Difference Algorithm, ViBe Algorithm.

Extracting Background Algorithms' Theory

I wrote a blog about these algorithms' theory. And here is the web address: http://blog.csdn.net/ajianyingxiaoqinghan/article/details/72628402

Files Introduction

• src - Source Codes' Path
  • FramesDifference - source codes of Frame-Difference Algorithm
  • GaussBGDifference - source codes of Gauss-Background-Difference Algorithm
  • ViBe - source codes of ViBe Algorithm
• Image - the Path of Screenshot of Test Programs
• Video - the Path of Test Video
• CMakeLists.txt - CMake File of this Project

Tutorial for Generating this Project

1. My Working Environment

• Operating System: Ubuntu 14.04 LTS
• Conditions before your cmake command:
  • have already done OpenCV's make & make install
  • have already done CMake's make & make install

Besides, I also wrote the tutorial blog of how to install OpenCV 2.4.9 in Ubuntu 14.04. Here are the websites: CSDN：http://blog.csdn.net/ajianyingxiaoqinghan/article/details/62424132 GitHub：upcAutoLang/Blog#1

2. CMake this Project

Open a terminal and enter in the path of folder named GLCM_OpenCV, then input commands like below:

cmake ./
make

Then you will build this project.

The path of binary files - /BackgroundSplit-OpenCV/build/bin The path of library files - /BackgroundSplit-OpenCV/build/lib

Test Results

I run the algorithm test program by using image whose path is /GLCM_OpenCV/image/miska.jpg, and the result is like below:

I run these 3 kinds of Algorithms by using video whose path is /BackgroundSplit-OpenCV/Video/Camera Road 01.avi, and 3 kinds of Algorithms' results are like below: the result of Frame-Difference Algorithm: the result of Gauss-Background-Difference Algorithm: the result of ViBe Algorithm:

**P.S: the efficiency of ViBe Algorithm: ** the result of Debug Version:
