Around the incorrect ones.for example the entire 3*3 surroundings of a single mismatch lie above the given threshold. To counter this effect we performed a 3*3 dilatation on the elimination zone to recover the well-matches areas
In the course of an iterative process the same procedure would also be possible using the length of the creep vectors as a disqualifier instead of the angle. However one iterative with angle values was sufficient here
