I'm developing Hololens apps which use the ImageTarget functionality (but posted the thread in here because this seems to be more global).
I'm having an issue with the precision of Vuforia's recognition however. It seems that the algorithm allows detection when only some percentage of the feature points is detected. I came across this problem while manipulating QR codes. I indeed tested if the same code with only a part missing/altered could lead into a false positive, and it did (see the image linked to this thread, the altered one is detected as the original one).
Is there a way to tighten the conditions for the detected state to occur, at current release?
Then, if possible, an adjustable parameter accessible via the Unity editor in a future release would be a great feature for developpers who need precision detection.
