Description

set_rejection_params_ocr_class_mlpset_rejection_params_ocr_class_mlpSetRejectionParamsOcrClassMlpSetRejectionParamsOcrClassMlpset_rejection_params_ocr_class_mlp sets the rejection class parameters of the OCR classifier passed in OCRHandleOCRHandleOCRHandleOCRHandleocrhandle. The parameter to be set is specified with GenParamNameGenParamNameGenParamNamegenParamNamegen_param_name. Its value is specified with GenParamValueGenParamValueGenParamValuegenParamValuegen_param_value. 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_mlpCreateOcrClassMlpCreateOcrClassMlpcreate_ocr_class_mlp. For details on how to specify a rejection class, see set_rejection_params_class_mlpset_rejection_params_class_mlpSetRejectionParamsClassMlpSetRejectionParamsClassMlpset_rejection_params_class_mlp.

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

During execution of this operator, access to the value of this parameter must be synchronized if it is used across multiple threads.

Parameters

Result

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