criteria for identifying the enough match and computing Homography matrix!?

[Masoumehrahimi]

hi
in http://introlab.github.io/find-object/, in the second photo (15 in 52 out), it is mentioned that: "this will also tell if there is enough matches to compute the Homography". how much is the rate/ value for considering enough matches? based on which criteria, it will identify that the enough match has occurred?

thanks

Hi

Would you please guide me in this regard?

thanks

In parameters, see Homography->minimumInliers for the miminum matched required to compute the homography. This will also used to reject the homography if the number of inliers are below that threshold.
