Description

read_ocr_class_svmread_ocr_class_svmread_ocr_class_svmReadOcrClassSvmReadOcrClassSvm reads an OCR classifier that has been stored with write_ocr_class_svmwrite_ocr_class_svmwrite_ocr_class_svmWriteOcrClassSvmWriteOcrClassSvm. Since the training of an OCR classifier can consume a relatively long time, the classifier is typically trained in an offline process and written to a file with write_ocr_class_svmwrite_ocr_class_svmwrite_ocr_class_svmWriteOcrClassSvmWriteOcrClassSvm. In the online process the classifier is read with read_ocr_class_svmread_ocr_class_svmread_ocr_class_svmReadOcrClassSvmReadOcrClassSvm and subsequently used for classification with do_ocr_single_class_svmdo_ocr_single_class_svmdo_ocr_single_class_svmDoOcrSingleClassSvmDoOcrSingleClassSvm or do_ocr_multi_class_svmdo_ocr_multi_class_svmdo_ocr_multi_class_svmDoOcrMultiClassSvmDoOcrMultiClassSvm.

Result

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