Description

get_params_ocr_class_svmget_params_ocr_class_svmGetParamsOcrClassSvmGetParamsOcrClassSvmget_params_ocr_class_svm returns the parameters of an OCR classifier that were specified when the classifier was created with create_ocr_class_svmcreate_ocr_class_svmCreateOcrClassSvmCreateOcrClassSvmcreate_ocr_class_svm. This is particularly useful if the classifier was read with read_ocr_class_svmread_ocr_class_svmReadOcrClassSvmReadOcrClassSvmread_ocr_class_svm. The output of get_params_ocr_class_svmget_params_ocr_class_svmGetParamsOcrClassSvmGetParamsOcrClassSvmget_params_ocr_class_svm can, for example, be used to check whether a character to be read is contained in the classifier. For a description of the parameters, see create_ocr_class_svmcreate_ocr_class_svmCreateOcrClassSvmCreateOcrClassSvmcreate_ocr_class_svm.

Execution Information

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

Result

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