Méthode	Description
MCvSURFParams ( double hessianThreshold, bool extended ) : System	Creage CvSURFParams with the specific value
MCvSURFParams ( double hessianThreshold, bool extended, int nOctaves, int nOctaveLayers ) : System	Create CvSURFParams with the specific value

Method Details

MCvSURFParams() public méthode

Creage CvSURFParams with the specific value

public MCvSURFParams ( double hessianThreshold, bool extended ) : System
hessianThreshold	double	Only features with keypoint.hessian larger than this are extracted.
extended	bool	/// False means basic descriptors (64 elements each), /// True means extended descriptors (128 elements each) ///
Résultat	System

MCvSURFParams() public méthode

Create CvSURFParams with the specific value

public MCvSURFParams ( double hessianThreshold, bool extended, int nOctaves, int nOctaveLayers ) : System
hessianThreshold	double	Only features with keypoint.hessian larger than this are extracted.
extended	bool	/// False means basic descriptors (64 elements each), /// True means extended descriptors (128 elements each) ///
nOctaves	int	/// The number of octaves to be used for extraction. /// With each next octave the feature size is doubled ///
nOctaveLayers	int	/// The number of layers within each octave ///
Résultat	System

Property Details

Extended public_oe property

False means basic descriptors (64 elements each), True means extended descriptors (128 elements each)

public bool Extended
Résultat	bool

HessianThreshold public_oe property

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

public double HessianThreshold
Résultat	double

NOctaveLayers public_oe property

The number of layers within each octave

public int NOctaveLayers
Résultat	int

NOctaves public_oe property

The number of octaves to be used for extraction. With each next octave the feature size is doubled

public int NOctaves
Résultat	int

Upright public_oe property

Upright SURF

public bool Upright
Résultat	bool
