set_rejection_params_ocr_class_mlpT_set_rejection_params_ocr_class_mlpSetRejectionParamsOcrClassMlpSetRejectionParamsOcrClassMlp (Operator)
Name
set_rejection_params_ocr_class_mlpT_set_rejection_params_ocr_class_mlpSetRejectionParamsOcrClassMlpSetRejectionParamsOcrClassMlp — Set the rejection class parameters of an OCR classifier.
Signature
Description
set_rejection_params_ocr_class_mlpset_rejection_params_ocr_class_mlpSetRejectionParamsOcrClassMlpSetRejectionParamsOcrClassMlpSetRejectionParamsOcrClassMlp sets the rejection class
parameters of the OCR classifier passed in OCRHandleOCRHandleOCRHandleOCRHandleOCRHandle. The
parameter to be set is specified with GenParamNameGenParamNameGenParamNameGenParamNamegenParamName. Its
value is specified with GenParamValueGenParamValueGenParamValueGenParamValuegenParamValue. For some OCR
applications it is important to know, if a letter to be classified
is similar to the training set or not. If a letter is different to
the training set, then it can be classified a rejection class. This
additional rejection class must be specified as an additional
character in create_ocr_class_mlpcreate_ocr_class_mlpCreateOcrClassMlpCreateOcrClassMlpCreateOcrClassMlp. For details on how to
specify a rejection class, see

Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
This operator modifies the state of the following input parameter:
During execution of this operator, access to the value of this parameter must be synchronized if it is used across multiple threads.

Result
If the parameters are valid, the operator
set_rejection_params_ocr_class_mlpset_rejection_params_ocr_class_mlpSetRejectionParamsOcrClassMlpSetRejectionParamsOcrClassMlpSetRejectionParamsOcrClassMlp returns the value
2 (H_MSG_TRUE). If necessary, an exception is raised.
