Hi, I'm pretty new to CV.
I want to match img1 and img2 based on ORB descriptors, and RANSAC to select the best matches. This part is okey.
Then I want to match img2 and img3, but ONLY with the descriptors in img2 who got a match with img1. Then I want to match img3 and img4, but ONLY with the descriptors in img3 who got a match with img2. Then I want to match img4 and img5, but ONLY with the descriptors in img4 who got a match with img3. And so on (it's a video file, and imgX = frameX).
So, is there a way to sort out the descriptors who got a match with the other image?
The main goal is to track the descriptors.
