Parameters
Expected
Threshold for assessing the result. It indicates to what extent the area detected within the
searched ROI must match the sample image in order to be considered valid (100% perfect
match, 0% … ).
Min Count
Setting specifying the minimum number of patterns that can be detected.
Max Count
Setting specifying the maximum number of patterns that can be detected.
Sensitivity
Identifies the accuracy used when searching for the pattern inside the captured image. The
higher the desired quality, the longer is the time required to complete image processing. Vice
versa, the higher the desired speed, the lower the match quality.
Result
If the number of identified patterns falls within the range set by the user (min. and max. values),
the inspection outcome will be positive. If it is not so, result will be negative.
Example
Say that we wish to add an inspection of the "pattern count" type to current inspection, so as to
make sure that the logo is present on the box.
