HI,i use hogdescriptor to compute a pic hog. I can run my code in win32 envrionment, but throw a exception when i use mfc environment. why do it take place like this?

#pragma region test_HOG
                IplImage* trainImg = cvCreateImage(cvSize(64, 64), 8, 3);
        IplImage* test_Image=cvLoadImage("test2.jpg");
        cv::Mat ima(test_Image,0);
        //cvResize(ima, imat);     
        BOOL EmptyAllSet();//clean the sd
        hog->compute(test_Image, descriptors, Size(1, 1), Size(0, 0)); 
#pragma endregion test_HOG
