Hi @crackwitz,
That totally makes sense. Let me rephrase my question a little: Is there an approach that yields a similar output like LK optical flow but operates on keypoints only? Of course I can take blob detections from successive frames and create tracks manually, but that doesn’t check whether there’s a plausible connection between those detections from frame to frame if multiple blobs are detected. I’m wondering if there’s an algorithm that e.g. estimates a motion vector for each point and then finds matching points in the next frame or implements some similar validation approach?
I’m thinking of this like motion capture approaches used in film, where not the image of the person moving is tracked but rather a few very high-contrast points.
Best,
West
