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.
