CogOCRMaxClassifier.Execute Method (CogOCRMaxChar, CogOCRMaxClassifierRunParams)

CogOCRMaxClassifier Execute Method (CogOCRMaxChar, CogOCRMaxClassifierRunParams)

Cognex VisionPro 9.8

Classify a single character. The input CogOCRMaxChar contains an image of the character, as well as a Metrics property which define the character's mark rectangle and cell rectangle. Typically the input CogOCRMaxChar.CharacterCode is set to Unknown because the character has not yet been classified.

Parameters

character: Type: Cognex.VisionPro.OCRMax CogOCRMaxChar
The character to be classified.

runParams: Type: Cognex.VisionPro.OCRMax CogOCRMaxClassifierRunParams
The run params that specify how to perform classification.

Return Value

Type: CogOCRMaxClassifierPositionResult

Exceptions

Exception	Condition
CogSecurityViolationException
CogOCRMaxClassifierParamsException	Thrown if: any character's image is not allocated any character's cell rect is not specified
CogTimeoutExpiredException	Thrown if the Timeout expired.
ArgumentNullException	Thrown if character is null. Thrown if runParams is null.

Remarks

Note that space characters are a special case. The OCRMax Classifier does not classify space characters. Instead the classifier input (cf. the segmenter output) is responsible for deciding if a particular character is a space. The classifier simply "passes through" space characters and their associated scores. Space characters are not assigned alternative characters, and the confidence score is set to be equal to the regular score in the classifier output.

If the input's CogOCRMaxChar.CharacterCode == 20 (space) the classifier will automatically classify the character as a space. The space character's score and confidence score will be set to the 1 in the classifier output.
