+ The Keypoint Class
+
+ The class instance stores a keypoint, i.e. a point feature found by one of many available keypoint detectors, such as
+ Harris corner detector, cv::FAST, cv::StarDetector, cv::SURF, cv::SIFT, cv::LDetector etc.
+
+ The keypoint is characterized by the 2D position, scale
+ (proportional to the diameter of the neighborhood that needs to be taken into account),
+ orientation and some other parameters. The keypoint neighborhood is then analyzed by another algorithm that builds a descriptor
+ (usually represented as a feature vector). The keypoints representing the same object in different images can then be matched using
+ cv::KDTree or another method.
