Detailed Description

Data structure for salient point detectors.

coordinates of the keypoint

diameter of the meaningful keypoint neighborhood

// C++ code:

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.

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

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

object id that can be used to clustered keypoints by an object they belong to
