Description

get_params_ocr_class_cnnget_params_ocr_class_cnnGetParamsOcrClassCnnGetParamsOcrClassCnnget_params_ocr_class_cnn returns the parameters GenParamNameGenParamNameGenParamNamegenParamNamegen_param_name of an OCR classifier OCRHandleOCRHandleOCRHandleOCRHandleocrhandle in GenParamValueGenParamValueGenParamValuegenParamValuegen_param_value. This is particularly useful if the classifier was read with read_ocr_class_cnnread_ocr_class_cnnReadOcrClassCnnReadOcrClassCnnread_ocr_class_cnn. The output of get_params_ocr_class_cnnget_params_ocr_class_cnnGetParamsOcrClassCnnGetParamsOcrClassCnnget_params_ocr_class_cnn can, for example, be used to check whether a character to be read is contained in the classifier.

Possible values for GenParamNameGenParamNameGenParamNamegenParamNamegen_param_name are:

'characters'"characters""characters""characters""characters":

Returns a list of all trained symbols which may be recognized by the CNN-based OCR classifier. Note that if 'characters'"characters""characters""characters""characters" is specified then no other generic parameter is allowed. Otherwise an exception is thrown.

Execution Information

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.

Parameters

OCRHandleOCRHandleOCRHandleOCRHandleocrhandle (input_control)  ocr_cnn → HOCRCnn, HTupleHHandleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)

Handle of the OCR classifier.

GenParamNameGenParamNameGenParamNamegenParamNamegen_param_name (input_control)  string(-array) → HTupleMaybeSequence[str]HTupleHtuple (string) (string) (HString) (char*)

A tuple of generic parameter names.

Default: 'characters' "characters" "characters" "characters" "characters"

List of values: 'characters'"characters""characters""characters""characters"

GenParamValueGenParamValueGenParamValuegenParamValuegen_param_value (output_control)  string(-array) → HTupleSequence[Union[int, str]]HTupleHtuple (integer / string) (int / long / string) (Hlong / HString) (Hlong / char*)

A tuple of generic parameter values.

Result

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