Description

Hi,

when I add a first point by clicking the mouse in lkdemo.exe, the application crashes during cornerSubPix. I isolated a small piece of code from lkdemo.cpp demonstrating the behaviour and reproducing that crash:

int main( int argc, char** argv ) {
TermCriteria termcrit(TermCriteria::COUNT|TermCriteria::EPS,20,0.03);
Mat image( 512, 512, CV_8UC3 );
Point2f point = Point2f(100,100);
vector<Point2f> corners;
corners.push_back(point);
cornerSubPix( image, corners, Size(5,5), Size(-1,-1), termcrit );
}

I found that corners vector is converted to a bad Mat containing 9 (!) points which will cause the error.

I compiled OpenCV using CMake and VisualStudio 2010 using default settings.
