KeyPoint
--------
.. ocv:class:: KeyPoint
Data structure for salient point detectors.
.. ocv:member:: Point2f pt
coordinates of the keypoint
.. ocv:member:: float size
diameter of the meaningful keypoint neighborhood
.. ocv:member:: float angle
computed orientation of the keypoint (-1 if not applicable). Its possible values are in a range [0,360) degrees. It is measured relative to image coordinate system (y-axis is directed downward), ie in clockwise.
.. ocv:member:: float response
the response by which the most strong keypoints have been selected. Can be used for further sorting or subsampling
.. ocv:member:: int octave
octave (pyramid layer) from which the keypoint has been extracted
.. ocv:member:: int class_id
object id that can be used to clustered keypoints by an object they belong to
