描述

算子 write_ocr_trainf_imagewrite_ocr_trainf_imageWriteOcrTrainfImageWriteOcrTrainfImageWriteOcrTrainfImagewrite_ocr_trainf_image is used to prepare the training with the operator trainf_ocr_class_mlptrainf_ocr_class_mlpTrainfOcrClassMlpTrainfOcrClassMlpTrainfOcrClassMlptrainf_ocr_class_mlp or trainf_ocr_class_svmtrainf_ocr_class_svmTrainfOcrClassSvmTrainfOcrClassSvmTrainfOcrClassSvmtrainf_ocr_class_svm。Hereby regions, representing characters, including their gray values (region and pixel) and the corresponding class name will be written into a file. An arbitrary number of regions within one image is supported. For each character (region) in CharacterCharacterCharacterCharactercharactercharacter the corresponding class name must be specified in ClassClassClassClassclassValclass. If no file extension is specified in TrainingFileTrainingFileTrainingFileTrainingFiletrainingFiletraining_file the extension '.trf' is appended to the file name. In contrast to write_ocr_trainfwrite_ocr_trainfWriteOcrTrainfWriteOcrTrainfWriteOcrTrainfwrite_ocr_trainf one image per character is passed. The domain of this image defines the pixels which belong to the character. The file format can be defined by the parameter 'ocr_trainf_version'"ocr_trainf_version""ocr_trainf_version""ocr_trainf_version""ocr_trainf_version""ocr_trainf_version" of the operator set_systemset_systemSetSystemSetSystemSetSystemset_system。
