Remarks

You should supply an acceptance threshold value such that no actual instance of a pattern will receive a score less than the threshold. SearchMax assumes that any location in the search image which receives a value less than this threshold is not an actual instance of the pattern.

The ConfusionThreshold must be greater than or equal to the AcceptThreshold. If this property is set to a value greater than ConfusionThreshold, the ConfusionThreshold is set to the new value.
