I suggest improving enrollment procedure. It should stitch big image from several small images and use it later for comparison (using whatever algorithm - minutiae algo also may work). On Mon, Jan 29, 2018 at 7:38 AM, Hans de Goede wrote: > Hi, > > On 23-01-18 22:58, Igor Filatov wrote: >> >> I'v

I'm pretty sure it would need to be in C. You shouldn't need to REwrite a lot of code. It would depend on the algorithm but I'm guessing libfprint would interface with it pretty much like it does with nbis: get image from driver, submit image to nbis to get minutiae, compare to saved minutiae ( htt

Hi, Let’s assume I’d like to take a look at it (I am indeed quite interested). Would I have to write the algorithm in C (I am, as mentioned, not quite good in C and I don’t think that C is the perfect language for algorithmic)? And would I have to rewrite the existing code or could I just repl

Well yes, treating these readers as swipe devices does seem awkward. But that was the only way of making it work short of implementing a new recognition algo, which seemed like too much at the time. In fact, the current one is also a 3rd party lib. The authors of libfprint have considered an altern

Hello Igor, where do I get the fprint_demo tool from? I failed to find it. The overall image looks alright, but still not very good - I attached an image of mine. I made a really careful swipe and now it detects my finger in about 50% of the cases - still not very good, but I guess I'll just
