KeyPoint(Point2f, float, float, float, int, int)

Data structure for salient point detectors

public KeyPoint(Point2f Pt, float Size, float Angle = -1, float Response = 0, int Octave = 0, int ClassId = -1)

Parameters

Pt Point2f

Coordinate of the point

Size float

Feature size

Angle float

Feature orientation in degrees (has negative value if the orientation is not defined/not computed)

Response float

Feature strength (can be used to select only the most prominent key points)

Octave int

Scale-space octave in which the feature has been found; may correlate with the size

ClassId int

Point class (can be used by feature classifiers or object detectors)
