@ppwwyyxx When I read the source code. I have a proble. How to calculate confidence in the MatchInfo class when I already know the number of correctly matched interior points. The following is the output after the match, I can understand how to compute ninliers, but do not know how to compute conf?

@ppwwyyxx Thanks for your reply. What does the confidence in the MatchInfo mean? If I want to use the Surf Match. How can I compute the value of the confidence?

Confidence: the feeling or belief that one can rely on someone or something.

In this context: the feeling or belief that one can rely on the match.

It is computed in the above code.
