Feature Matching Problem
Image matching is an important task in computer vision. Real-world objects may be captured on different photos from any angle with any lightning conditions and may be occluded. But while images contain the same objects they must be categorized accordingly. For this purpose, computer vision gives us invariant feature extractors that help to match objects on different images
Detectors, Descriptors, and Matchers
Image matching is a three-step algorithm. Fortunately, they are all covered in the OpenCV library
