描述

read_ocr_class_mlpread_ocr_class_mlpReadOcrClassMlpReadOcrClassMlpReadOcrClassMlpread_ocr_class_mlp reads an OCR classifier that has been stored with write_ocr_class_mlpwrite_ocr_class_mlpWriteOcrClassMlpWriteOcrClassMlpWriteOcrClassMlpwrite_ocr_class_mlp. 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_mlpwrite_ocr_class_mlpWriteOcrClassMlpWriteOcrClassMlpWriteOcrClassMlpwrite_ocr_class_mlp. In the online process the classifier is read with read_ocr_class_mlpread_ocr_class_mlpReadOcrClassMlpReadOcrClassMlpReadOcrClassMlpread_ocr_class_mlp and subsequently used for classification with do_ocr_single_class_mlpdo_ocr_single_class_mlpDoOcrSingleClassMlpDoOcrSingleClassMlpDoOcrSingleClassMlpdo_ocr_single_class_mlp or do_ocr_multi_class_mlpdo_ocr_multi_class_mlpDoOcrMultiClassMlpDoOcrMultiClassMlpDoOcrMultiClassMlpdo_ocr_multi_class_mlp.

HALCON provides a number of pretrained OCR classifiers (see the “Solution Guide I”, chapter 'OCR', section 'Pretrained OCR Fonts'). These pretrained OCR classifiers make it possible to read a wide variety of different fonts without the need to train an OCR classifier. Note that the pretrained OCR classifiers were trained with symbols that are printed dark on light.

This operator returns a handle. Note that the state of an instance of this handle type may be changed by specific operators even though the handle is used as an input parameter by those operators.
