Characteristic
Sub-Pixel The sub-pixel parameter defines whether the position and the orien-
tation of the detected model will be read out with accuracy down to
the pixel or the sub-pixel.
--- The object’s coordination and angle of rota-
tion are read out with an accuracy of down to
1 pixel.
Interpolation When interpolation is activated, the algorithm
examines the position of the object on the ba-
sis of neighboring pixels, angles and scaling
around the best coincidence match. The results
are accurate down to roughly one twentieth of
a pixel.
Interpolation is very fast and can be activated
for most applications.
Smallest Squares The smallest squares parameter works against
the interpolation parameter. This function re-
quires a great deal of computing time.

Max. Deforma-
tion 1
Sometimes no objects are found, or only ob-
jects with a minimal coincidence value, because
they’re highly deformed relative to the taught-in
model. The max. deformation parameter speci-
fies by how many pixels the detected object
can differ from the taught-in object. Selection
can be made between the Max. Deformation 1
and the Max. Deformation 2 parameters.

Aggressiveness “Aggressiveness” of the search heuristics (0: reliable but slow, 1:
fast but matches may be overlooked).
