描述

该算子 read_ocrread_ocrReadOcrReadOcrReadOcrread_ocr reads an OCR classifier from a file FileNameFileNameFileNameFileNamefileNamefile_name. This file will hereby be searched in the directory ($HALCONROOT/ocr/) as well as in the currently used directory. If too many classifiers have been loaded, an error message will be displayed.

运行信息

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.
