This repository is the C++ Source Code of GLCM, which is based on OpenCV libraries after I learn about the theory of GLCM (Gray-level Co-occurrence Matrix).

GLCM's Theory

I wrote a blog about GLCM's theory. And here is the web address: http://blog.csdn.net/ajianyingxiaoqinghan/article/details/71552744

Files Introduction

• src - Source Codes' Path
  • glcm.h - GLCM algorithm's head file source code
  • glcm.cpp - GLCM algorithm's C++ source code
  • main.cpp - GLCM algorithm's test program's source code
• lib - the Generating Path of Dynamic-Link Library
• image - the Path of Images for Algorithm Test Program
• CMakeLists.txt - CMake File of this Project

Tutorial for Generating this Project

1. My Working Environment

• Operating System: Ubuntu 14.04 LTS
• OpenCV Version: 2.4.9
• 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 - /GLCM_OpenCV/build/bin The path of library files - /GLCM_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:

the result of Debug Version:

Time of Magnitude Gray Image: 1.38906ms
Time of Calculate Texture Features of the whole Image: 4126.57ms

the result of Release Version:

Time of Magnitude Gray Image: 0.452412ms
Time of Calculate Texture Features of the whole Image: 1291.15ms
