| Member name | Value | Description | |
|---|---|---|---|
| NotRead | 1 |
The Tool identified the position of a character in the image; however,
the character at this position could not be "read" by the Classifier.
This is usually because the Classifier has not been properly trained
from a Font yet.
NotRead position results have their character codes set to Unknown or Space as dictated by the Segmenter. NotRead is an important state when training the OCRMax Classifier as NotRead position results can be manually labeled with the correct character code and used to build up the Font. | |
| Read | 2 | The OCRMax Tool successfully read the character at this position. | |
| Confused | 3 |
The Tool identified a character that scored high enough to be a good read
(above the accept threshold), however, a different character scored close
enough to the same score (within the confusion threshold) such that the
tool isn't confident that it picked the correct character.
Confused = | ScorePrimary - ScoreSecondary | < ConfidenceThreshold ScorePrimary < ScoreSecondary can only be true when Fielding's ConfusionMetric property is set to AllCharactersInFont. Confused status may also be returned if an "internal validation check" performed by the Tool has failed. In this case the result's ConfusionExplanation property will be set to ClassificationValidationFailure to notify you that this has occurred The internal validation step can be disabled by setting the Tool.Classifier.TrainParams.Algorithm property to Basic. | |
| Mismatch | 4 |
The tool found a character that does not match the fielding which scored
much higher than any characters that do match the fielding. It is likely
that a character that does _not_ match the fielding was printed at this
position.
Mismatch = ScoreNotMatching - ScoreMatching > ConfidenceThreshold Mismatch status is only returned if the Fielding's ConfusionMetric property is set to AllCharactersInFont. | |
| Failed | 5 | No characters scored high enough (above the accept threshold) to be considered a good read. |
