Common interface of 2D image Feature Detectors
Class for detecting keypoints in images.
Feature detectors in OpenCV have wrappers with a common interface that enables you to easily switch between different algorithms solving the same problem. All objects that implement keypoint detectors inherit the FeatureDetector interface.
detector = cv.FeatureDetector('ORB');
keypoints = detector.detect(img);
