Public Shared Function cvSURFParams ( _
	hessianThreshold As Double, _
	extended As Integer _
) As SURFDetector
Visual C++
public:
static SURFDetector^ cvSURFParams(
	double hessianThreshold, 
	int extended
)

Parameters

hessianThreshold
Type: System..::..Double
only features with keypoint.hessian larger than that are extracted. good default value is ~300-500 (can depend on the average local contrast and sharpness of the image). user can further filter out some features based on their hessian values and other characteristics
extended
Type: System..::..Int32
0 means basic descriptors (64 elements each), 1 means extended descriptors (128 elements each)
