Feature detection (SIFT, SURF, ORB) – OpenCV 3.4 with python part 1
#Pyresearch #opencv #opencvpython
We’re going to learn in this tutorial how to find features on an image.
We will test three different algorithms: Sift, Orb, and Surf
1- Detecting features - Corners
2 - Feature matching using ORB (Oriented FAST and Rotated BRIEF)
Each one of them has pros and cons, it depends on the type of images some algorithms will detect more features than another.
SIFT and SURF are patented so not free for commercial use, while ORB is free.SIFT and SURF detect more features than ORB, but ORB is faster.
