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

set_rejection_params_ocr_class_mlp( : : OCRHandle, GenParamName, GenParamValue : )

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 set_rejection_params_class_mlpset_rejection_params_class_mlpSetRejectionParamsClassMlpSetRejectionParamsClassMlpSetRejectionParamsClassMlp.

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:

OCRHandleOCRHandleOCRHandleOCRHandleOCRHandle

The value of this parameter may not be shared across multiple threads without external synchronization.

Parameters

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.
