CogOCRMaxTuneData.Tune Method

CogOCRMaxTuneData Tune Method

Cognex VisionPro

Performs a full Tune of the CogOCRMaxTuneRecords contained in this object.

After calling this function the TuneData will be in the "tuned" state.

When in the tuned state the user can call GetTunedSegmenter(), and GetTunedFont() to extract the tuned OCRMax operators.

Note that performing a full Tune may produce different results than calling the incremental AutoTune() on the same set of CogOCRMaxTuneRecords data.

Parameters

tuneParams: Type: Cognex.VisionPro.OCRMax CogOCRMaxTuneParams
A CogOCRMaxTuneParams object which controls the AutoCorrect process.

segmenter: Type: Cognex.VisionPro.OCRMax CogOCRMaxSegmenter
The current CogOCRMaxSegmenter to use as a hint or starting point for the AutoCorrect process.

classifierTrainParams: Type: Cognex.VisionPro.OCRMax CogOCRMaxClassifierTrainParams
The current CogOCRMaxClassifierTrainParams, this argument is ignored by AutoCorrect.

classifierRunParams: Type: Cognex.VisionPro.OCRMax CogOCRMaxClassifierRunParams
The current CogOCRMaxClassifierRunParams, this argument is ignored by AutoCorrect.

Exceptions

Exception	Condition
ArgumentNullException	Thrown if tuneParams is null. Thrown if segmenter is null. Thrown if classifierTrainParams is null. Thrown if classifierRunParams is null.
InvalidOperationException	Thrown if tune data contains zero tune records.
CogOCRMaxInvalidTuneRecordException	Thrown if any tune record has an unallocated image Thrown if any tune record contains no character codes Thrown if any tune record has a character code which is the unknown character marker Thrown if any tune records has a mark rect which has an angle or skew greater than 45 degrees relative to the region Thrown if (number of mark rects != number of cell rects != number of character codes) for any tune record
