Of course I can understand that you can’t reveal any secrets about the “insides”! Neither do I want that nor did I get the impression that I was pressing for exactly that. On the contrary, I keep saying (in other threads) that neither can we expect those insider secrets nor do they interest me.
With one exception, and that is in which way settings influence the result and by extension performance (relevant here in this thread). I do not think that this is asking too much.
The whole debate only started out because there some unclear phrasings (to me anyway) that I wanted to clear up (or try to).
Mike said Preselector number doesn’t matter for performance (in this case rather RAM usage), which sounds logical because PRE means in my understanding something like temporary or preliminary. That would mean that the whole number of features should be used after the initial number defined in Preselector. In the quote I found in the help it gives a different impression as in that it sounds as if only the number defined in Preselector is used. That again lead to the question why there are more tie points in some images than the Preselector.
So to boil it down I think the question remains: Will all features defined by Max features per mpx/image be used or only the number defined by the Preselector features? I really can’t see why this would be considered an essential “insider information”. If it really is, then please say so and I shall leave you in peace…
