Writing MATLAB C-MEX Code

1.添加环境变量

2.为Matlab关联VS

下载并按说明添加5个文件，否则matlab会找不到VS

3.创建 opencv2matlab.cpp

 

#include <iostream>
#include <string>

#include "opencv2/opencv.hpp"

#include "mex.h"

// Matlab entry point function
void mexFunction( int nlhs, mxArray *plhs[], int nrhs, const mxArray*prhs[] )
{
    // Check if the input argument is legal
    if ( nrhs != 1 || !mxIsChar( prhs[0] ) )
    {
        mexErrMsgTxt("An image name should be given.\n");
    }
    
    // Get the name of the image
    int nStringLen;
    nStringLen = mxGetNumberOfElements(prhs[0]);
    std::string szImageName;
    szImageName.resize( nStringLen + 1 );
    
    mxGetString( prhs[0], &szImageName[0], nStringLen + 1 );
    
    // Read the image from file
    cv::Mat image;
    image = cv::imread( szImageName );
    
    // Show the image if it is successfully read from disk
    if ( !image.empty() )
    {
        cv::imshow( "Test Mex OpenCV", image );
    }
    else
    {
        mexErrMsgTxt("The specified image does not exist.\n");
    }
}

 

 

 

4.设置matlab路径为cpp，编译

mex opencv2matlab.cpp ...

-ID:\ProgramFiles\OpenCV\OpenCV-2.4.8\opencv\build\include ...

-LD:\ProgramFiles\OpenCV\OpenCV-2.4.8\opencv\build\x64\vc12\lib ...

-lopencv_contrib248 ...

-lopencv_core248 ...

-lopencv_legacy248 ...
