OpenCV cvSmooth not working in Qt, but OK in Visual C++ 2008

[aoikyou]

I am using Qt with OpenCV 2.3.1 (Qt version: Qt 4.8.0 for Desktop - MSVC2008, Tool Chain: Visual C++ Compiler 9.0 (x86)).
I am trying to run a simple tutorial example:



#include <QtGui/QApplication>
#include <cv.h>
#include <highgui.h>

int main(int argc, char *argv[])
{
QApplication a(argc, argv);

IplImage* img = 0;
img=cvLoadImage("angrybird.jpg");

// create a window
cvNamedWindow("mainWin", CV_WINDOW_AUTOSIZE);
cvMoveWindow("mainWin", 100, 100);

// show the image
cvShowImage("mainWin", img );


//cvWaitKey(0);
IplImage* img2 = cvCreateImage(cvGetSize(img),IPL_DEPTH_8U,3);
cvSmooth( img, img2, CV_GAUSSIAN, 3, 3 );
cvNamedWindow("Smooth", CV_WINDOW_AUTOSIZE);
cvMoveWindow("Smooth", 200, 200);
cvShowImage("Smooth", img2 );
cvWaitKey(0);

// release the image
cvReleaseImage(&img );
cvReleaseImage(&img2 );
return a.exec();
}


When I run it, I got the error message:


The program has unexpectedly finished.
... exited with code -1073741515


The code run fine though if I comment out the cvSmooth() line.

I believe I have the correct .pro file

I was thinking it might be due to missing dll. But when I test the same code in Visual Studio 2008, it works fine with cvSmooth() there and smooth the image as it suppose to do. If it is a dll problem, VC++ code shouldn't work either, isn't it?
Here is the VC++ code:



// testOpenCV.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"
#include <math.h>
#include <cv.h>
#include <highgui.h>

int _tmain(int argc, _TCHAR* argv[])
{
IplImage* img = 0;
img=cvLoadImage("angrybird.jpg");

// create a window
cvNamedWindow("mainWin", CV_WINDOW_AUTOSIZE);
cvMoveWindow("mainWin", 100, 100);
// show the image
cvShowImage("mainWin", img );

//cvWaitKey(0);

IplImage* img2 = cvCreateImage(cvGetSize(img),IPL_DEPTH_8U,3);
cvSmooth( img, img2, CV_GAUSSIAN, 3, 3 );
cvNamedWindow("Smooth", CV_WINDOW_AUTOSIZE);
cvMoveWindow("Smooth", 200, 200);
cvShowImage("Smooth", img2 );
cvWaitKey(0);
// release the image
cvReleaseImage(&img );
cvReleaseImage(&img2 );
return 0;
}



I am now run out of idea where to look for the problem. I will appreciate if anyone can point me to a new direction.
Thanks.

BTW, I tried the same thing on two machines, one is a desktop at work and another is a laptop, both running Windows 7. Got the same result on both machines: VC++ version runs fine, the Qt one is not working.

Anyone has experienced similar problem before?

I would really appreciate if someone try the Qt code above and see if they got the same problem. Thanks.

hi
did you found any answer ?

[aoikyou]

No. For now, I switch back to VC++ and am not using Qt for anything OpenCV. I still wish I could use Qt though.
Did you try using cvSmooth in Qt and got similar problem?
