I'm playing with "feature matching" in OpenCV. For different types of matching methods, we need to define a condition (i.e. OpenCV – SIFT SURF ORB tutorial MIN_MATCH_COUNT = 10) regarding the minimum number of matches.
I'm wondering if there is any kind of standard or golden standard method or criteria for setting this condition? How can / should we technically get this sort of threshold or condition?
Even a rule of thumb suggested would be help.
Thank you so much,
