What is the sampling method used by cv2.SIFT.detect?
Hi,
I'm new to OpenCV and SIFT algorithm. I'm using the python version of the library. I know that I can create lots of KeyPoint objects manually and send them to the cv2.SIFT.compute method to get their SIFT descriptors. Although, OpenCV offers another method (cv2.SIFT.detect) to automatically detect a set of KeyPoint objects, given an image.
My question is: what is the sampling method adopted by the cv2.SIFT.detect method?
Additionally: where in the literature can I find a detailed description of such method?
Best regards!
