Description

The operator read_ocrread_ocrReadOcrread_ocrReadOcrReadOcr reads an OCR classifier from a file FileNameFileNameFileNameFileNameFileNamefileName. 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.
