From the tutorial, I know how to SurfFeatureDetector with minHessian parameter. But when I create the detector with FeatureDetector::create, it does not provide me a way to set the parameter. I tried to call

FeatureDetector->setInt("minHessian", 100);

But I got no parameter name "minHessian" error in debug mode.

You can use the explicit constructor instead of the create method (haven't tested it, but should work like this):

cv::Ptr<cv::FeatureDetector> mysurf = cv::Ptr<cv::FeatureDetector>( new cv::SURF(100) );
