PatchCodeMinOccurrence - minimum score for a Patch Code barcode.
As the SDK scans an image it assigns a score to each barcode candidate. At the end of a scan, any candidates with a score >= PrefOccurrence are reported by the SDK. If no candidate meets this criteria then the SDK selects the candidate with the highest score and reports this barcode if it has a score >= MinOccurrence. Note that Patch Codes are only ever reported if the score is >= PatchCodeMinoccurrence.
Default value: 30
