I am having a hard time improving trackable. Putting some of them to greyscale & playing with contrast sometimes increase the star-rating, but decrease actual detection in the application.
Moreover, I often see "Number of trackables detected: 1" without having the 1 test tracker being detected, while it is on-screen. Then if I remove the tracker from camera range, it shows "Number of trackables detected: 0" without having found and/or lost a specific trackable.
I don't quite get it... how can it detect a trackable without finding & enabling it? What can we do to improve initial detection of trackers, if pure star-rating doesn't help?
