cv.FeatureDetector

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.

Example

detector = cv.FeatureDetector('ORB');
keypoints = detector.detect(img);
