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

    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:

    Qt Code: 
    1. #include <QtGui/QApplication>
    2. #include <cv.h>
    3. #include <highgui.h>
    4.  
    5. int main(int argc, char *argv[])
    6. {
    7.     QApplication a(argc, argv);
    8.  
    9.     IplImage* img = 0;
    10.     img=cvLoadImage("angrybird.jpg");
    11.  
    12.     // create a window
    13.     cvNamedWindow("mainWin", CV_WINDOW_AUTOSIZE);
    14.     cvMoveWindow("mainWin", 100, 100);
    15.  
    16.     // show the image
    17.     cvShowImage("mainWin", img );
    18.  
    19.  
    20.     //cvWaitKey(0);
    21.     IplImage* img2 = cvCreateImage(cvGetSize(img),IPL_DEPTH_8U,3);
    22.     cvSmooth( img, img2, CV_GAUSSIAN, 3, 3 );
    23.     cvNamedWindow("Smooth", CV_WINDOW_AUTOSIZE);
    24.     cvMoveWindow("Smooth", 200, 200);
    25.     cvShowImage("Smooth", img2 );
    26.     cvWaitKey(0);
    27.  
    28.     // release the image
    29.     cvReleaseImage(&img );
    30.     cvReleaseImage(&img2 );
    31.     return a.exec();
    32. }

    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:

    Qt Code: 
    1. // testOpenCV.cpp : Defines the entry point for the console application.
    2. //
    3.  
    4. #include "stdafx.h"
    5. #include <math.h>
    6. #include <cv.h>
    7. #include <highgui.h>
    8.  
    9. int _tmain(int argc, _TCHAR* argv[])
    10. {
    11. 	IplImage* img = 0;
    12. 	img=cvLoadImage("angrybird.jpg");
    13.  
    14. 	// create a window
    15.         cvNamedWindow("mainWin", CV_WINDOW_AUTOSIZE);
    16.         cvMoveWindow("mainWin", 100, 100);
    17. 	// show the image
    18.         cvShowImage("mainWin", img );
    19.  
    20. 	//cvWaitKey(0);
    21.  
    22. 	IplImage* img2 = cvCreateImage(cvGetSize(img),IPL_DEPTH_8U,3);
    23.         cvSmooth( img, img2, CV_GAUSSIAN, 3, 3 );
    24. 	cvNamedWindow("Smooth", CV_WINDOW_AUTOSIZE);
    25.         cvMoveWindow("Smooth", 200, 200);
    26. 	cvShowImage("Smooth", img2 );
    27. 	cvWaitKey(0);
    28. 	// release the image
    29.         cvReleaseImage(&img );
    30. 	cvReleaseImage(&img2 );
    31. 	return 0;
    32. }

    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.

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

    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.

    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?
