OMR_SENSE Enumeration

This setting defines the possible mark sensitivity values to be applied during the running of the RM_OMR checkmark recognition module. This setting may influence the accuracy of the recognition.

The higher the mark sensitivity setting, the more sensitive the recognition will be, i.e. even a small mark (just a few continuous black pixels) will cause the zone to be classified as "checked by respondent". The default sensitivity is suitable for well-printed questionnaires. Poor-quality forms should be avoided if possible, however lower sensitivity allows speckled or poorly printed documents to be processed successfully.
