KeyPoint Class Reference

Classes
union	Cv32suf

Public Types
typedef union GSLAM::KeyPoint::Cv32suf	Cv32suf

Public Member Functions
	KeyPoint (Point2f _pt, float _size, float _angle=-1, float _response=0, int _octave=0, int _class_id=-1)
	KeyPoint (float x, float y, float _size, float _angle=-1, float _response=0, int _octave=0, int _class_id=-1)
size_t	hash () const

Public Attributes
Point2f	pt
	coordinates of the keypoints
float	size
	diameter of the meaningful keypoint neighborhood
float	angle
	computed orientation of the keypoint (-1 if not applicable); < it's in [0,360) degrees and measured relative to < image coordinate system, ie in clockwise.
float	response
	the response by which the most strong keypoints have been selected. Can be used for the further sorting or subsampling
int	octave
	octave (pyramid layer) from which the keypoint has been extracted
int	class_id
	object class (if the keypoints need to be clustered by an object they belong to)
