Win7下Matlab中使用Visual Studio 2010编译Opencv的Mex文件

编译命令：

mex testmex.cpp -I"C:opencv24opencvbuildinclude" -I"C:opencv24opencvbuildincludeopencv" -L"C:opencv24opencvbuildx64vc10lib" -lopencv_core241 -lopencv_highgui241 -lopencv_imgproc241

这里关键是正确指定库文件查找路径

testmex.cpp内容

//file: testmex.cpp
//编译命令：mex testmex.cpp -I"C:opencv24opencvbuildinclude" -I"C:opencv24opencvbuildincludeopencv" -L"C:opencv24opencvbuildx64vc10lib" -lopencv_core241 -lopencv_highgui241 -lopencv_imgproc241
#include <iostream>
#include "mex.h"
#include "opencv2/opencv.hpp"
using namespace std;
using namespace cv;
void mexFunction(int nlhs, mxArray *plhs[], int nrhs, const mxArray *prhs[])
{
try
{
mexPrintf("come1n");
Mat src = cv::imread("d:\bird.jpg", CV_LOAD_IMAGE_GRAYSCALE), dst;
threshold(src, dst, 128.0, 255.0, CV_THRESH_BINARY);
imshow("Source", src);
cv::imshow("Result", dst);
cv::waitKey(0);
cvDestroyAllWindows();
mexPrintf("overn");
}
catch(const cv::Exception& ex)
{
char err[512];
sprintf(err, "Error:%s", ex.what());
mexPrintf(err);
}
mexPrintf("ok");
}
