Hi!When I compile the program,VC2005 always tell :"error C2198: 'cvEigenVV' : too few arguments for call".
Part of the code below:
void draw_oxfd_feature( IplImage* img, struct feature* feat, CvScalar color )
{
double m[4] = { feat-a, feat-b, feat-b, feat-c };
double v[4] = { 0 };
double e[2] = { 0 };
CvMat M;
CvMat V;
CvMat E;
double alpha, l1, l2;
/* compute axes and orientation of ellipse surrounding affine region */
cvInitMatHeader( &M, 2, 2, CV_64FC1, m, CV_AUTOSTEP );
cvInitMatHeader( &V, 2, 2, CV_64FC1, v, CV_AUTOSTEP );
cvInitMatHeader( &E, 2, 1, CV_64FC1, e, CV_AUTOSTEP );
cvEigenVV( &M, &V, &E, DBL_EPSILON );
l1 = 1 / sqrt( e[1] );
l2 = 1 / sqrt( e[0] );
alpha = -atan2( v[1], v[0] );
alpha *= 180 / CV_PI;
cvEllipse( img, cvPoint( feat-x, feat-y ), cvSize( l2, l1 ), alpha,
0, 360, CV_RGB(0,0,0), 3, 8, 0 );
cvEllipse( img, cvPoint( feat-x, feat-y ), cvSize( l2, l1 ), alpha,
0, 360, color, 1, 8, 0 );
cvLine( img, cvPoint( feat-x+2, feat-y ), cvPoint( feat-x-2, feat-y ),
color, 1, 8, 0 );
cvLine( img, cvPoint( feat-x, feat-y+2 ), cvPoint( feat-x, feat-y-2 ),
color, 1, 8, 0 );
// cvCircle(img,cvPoint(cvRound( feat-x ),cvRound( feat-y )),2, color, CV_FILLED, 8, 0);
cvCircle(img,cvPoint( cvRound( feat-x ), cvRound( feat-y )), 2,CV_RGB(0,255,0), CV_FILLED, 8, 0 );
}
How to solve the problem?Thank you!
