Property Value
Type: Double| Event Type | Reason |
|---|---|
| CogPMAlignRunParams Changed | Fires when the value of this property changes. The following state flag may be affected: |
| Exception | Condition |
|---|---|
| ArgumentException | The supplied value is less than 0.0 or greater than 1.0. |
The acceptance threshold on the score of a result. Only instances of the pattern that receive scores greater than or equal to this threshold are accepted. Valid range is from 0 to 1.
PMAlign may return more pattern instances than you specify if the instances have nearly equal scores that are only slightly below the accept threshold you specify.
After performing several test searches, you may be tempted to set the acceptance threshold value equal to or very close to the score of your test instance. Because PatMax searches first for coarse features, your expected instance may be filtered out if you set the acceptance threshold very close to the final score.
Default Value: 0.5
