 KeyPoint () 
 the default constructor


 KeyPoint (float x, float y, float size, float angle=1, float response=0, int octave=0, int class_id=1) 

 KeyPoint (Point2f pt, float size, float angle=1, float response=0, int octave=0, int class_id=1) 

size_t  hash () const 


Size_< float >  axes 
 the lengths of the major and minor ellipse axes


float  si 
 the integration scale at which the parameters were estimated


Matx23f  transf 
 the transformation between image space and local patch space


float  angle 

int  class_id 
 object class (if the keypoints need to be clustered by an object they belong to)


int  octave 
 octave (pyramid layer) from which the keypoint has been extracted


Point2f  pt 
 coordinates of the keypoints


float  response 
 the response by which the most strong keypoints have been selected. Can be used for the further sorting or subsampling


float  size 
 diameter of the meaningful keypoint neighborhood
