Hey! I'm trying to train a FernDescriptorMatcher. First i extract keypoints with SURF und then i call the train method with only one image(for test). I've been waiting several minutes but the training doesent end.

Why?

Make sure you have reasonable number of detected points (~100). In case you have too many, it may take a while dependent on your machine. But it is more likely there is something wrong, so you may want to debut the matcher and see what is going on.

Thanks for the answer. I've got 90 detected points on a 320x240 image. I've figured out that it takes a lot of time to train because of my computer. But now i've got a new question. Why does the FernDescriptorMatcher call the train() function again when i call the match() function. And how can i change that?
