Revision history [back]

I am new to opencv.. I have this simple code:

//Header files using namespace std; using namespace cv;

int main() {

Mat image;  Mat templ;
Mat result;
int method = CV_TM_SQDIFF; 

namedWindow( "result_window", CV_WINDOW_AUTOSIZE );

image = imread ("Image.png", 1 );
templ = imread ("template_m.png",1 ) ;

void matchTemplate (Mat image, Mat templ, Mat result, int method);

imshow ( "result_window", result ); return 0; }

But when i compile it it says abort() is called. Can anyone tell me what is the reason ??
