The problem still exists to use OpenCV 2.4.4 when compiled under x64+Debug+vc11 (though no problem under x64+Release+vc11). For example, if you want to call the following function, it will cause RtlFreeHeap error when it returns.

vector<float> get_color_histogram_of_image(Mat img)

{

vector<float> result;

/// Separate the image in 3 places ( B, G and R )
vector<Mat> bgr_planes;
split( img, bgr_planes );

/// Establish the number of bins
int histSize = 8;

/// Set the ranges ( for B,G,R) )
float range[] = { 0, 256 } ; //0~255 the upper boundary is exclusive
const float * histRange = { range };

bool uniform = true; 
bool accumulate = false;

Mat b_hist, g_hist, r_hist;

/// Compute the histograms:
calcHist( &bgr_planes[0], 1, 0, Mat(), b_hist, 1, &histSize, &histRange, uniform, accumulate );
calcHist( &bgr_planes[1], 1, 0, Mat(), g_hist, 1, &histSize, &histRange, uniform, accumulate );
calcHist( &bgr_planes[2], 1, 0, Mat(), r_hist, 1, &histSize, &histRange, uniform, accumulate );

/// stored in result
for (int i=0; i<histSize; i++)
    result.push_back(r_hist.at<float>(i, 0));
for (int i=0; i<histSize; i++)
    result.push_back(g_hist.at<float>(i, 0));
for (int i=0; i<histSize; i++)
    result.push_back(b_hist.at<float>(i, 0));

// release
//delete [2]histRange;

return result;

}

Hi, your code works well on my computer. Since OpenCV 2.43 does not work well with Visual Studio 2012, you have to use CMake to rebuild OpenCV 2.43. Have you done it? If you don't know how to rebuild it, tell me.

A great help. Thanks a lot. I had spent lot of time, though learned the hard way.

Only getting one problem in Debug : My system is windows 7 , 64 bit using VS 2010 and OpenCV 2.4.8

Error 1 error LNK1181: cannot open input file 'opencv_calib3d248d.dll' C:\Users\world\project\ver1\LINK ver1

I am trying this code : taken from web site

include "stdafx.h"

include <cv.h>

include <highgui.h>

include <math.h>

include <opencv2 highgui="" highgui.hpp="">

using namespace cv;

int main() { int k; VideoCapture cap = VideoCapture(0); while(1) { Mat img; cap >> img; imshow("image",img);

    k = waitKey(10);
    if (k == 27)         {
        break;
    }
}
return 0;

}

This program builds successfully in 64 bit , but on when I try to start without debugging I get this error OpenCV Error: Assertion failed (size.width>0 && size.height>0) in cv::imshow, file ......\opencv248\opencv\sources\modules\highgui\src\window.cpp, line 261 Press any key to continue . . . Similarly, I had developed a project in university times using 32 bit on the same system i.e., Win7, 32 bit with VS2010 , it works fine in VS2010 with same configuration but when I try to build it in 64 bit it gives same error message. Can you guide me. Rest all is OK. Thanks

Hi, Thanks for tutorial. I am following the steps mentioned in your tutorial. I keep on getting the following three message boxes during building "INSTALL.sln" project. These message boxes are generated by Visual Studio 2010. I have already closed my CMake window. I have Windows 7+ VS 2010+ CUDA 5.5 DIALOG-1:

DIALOG-2:

DIALOG-3:

My build process continues after these three dialog boxes. Only few projects are built after repeating this process for couple of hours.

Can anybody suggest any solution/idea to do it?

Regards,

Tariq

P.S: Its not a solution to the question originally asked. My problem is related to your tutorial....I can't add images in comments.!

If you have CUDA, in CMake, before second time clicking Configure button, I think you need set some buttons into checked state. Because my computer doesn't have CUDA...so I'm not very sure how to set up them. Hope it can help you guys who has CUDA.
