I'm doing the fingerprint recognition system, I'm stuck on matching part, I extracted minutiae, for each minutiae got their x,y position and orientation. Now, I don't know how to match two fingerprint image, how to know that two images belong one person. Here are minutiae extracted images: image description

Hi galimjan, how did you manage to extract minutiae' x,y position and euclidean distance? I am just looking for a way to do it in Open CV, would you kindly point me in the direction where I can get code to retrieve minutiae x, y positions and their euclidean distance?

First, convert the minutiea coordinates to a MatOfKeyPoint, then compute the (e.g. ORB) descriptors with a DescriptorExtractor. Now you can match them with a BFMatcher with e.g. knn.
