Description

write_ocr_class_knnwrite_ocr_class_knnWriteOcrClassKnnWriteOcrClassKnnWriteOcrClassKnnwrite_ocr_class_knn writes the k-NN classifier for an OCR task with the OCRHandleOCRHandleOCRHandleOCRHandleOCRHandleocrhandle to the file given by FileNameFileNameFileNameFileNamefileNamefile_name. If a file extension is not specified in FileNameFileNameFileNameFileNamefileNamefile_name the default extension '.onc' is appended to FileNameFileNameFileNameFileNamefileNamefile_name. write_ocr_class_knnwrite_ocr_class_knnWriteOcrClassKnnWriteOcrClassKnnWriteOcrClassKnnwrite_ocr_class_knn is typically called after the classifier has been trained with trainf_ocr_class_knntrainf_ocr_class_knnTrainfOcrClassKnnTrainfOcrClassKnnTrainfOcrClassKnntrainf_ocr_class_knn. The classifier can be read with read_ocr_class_knnread_ocr_class_knnReadOcrClassKnnReadOcrClassKnnReadOcrClassKnnread_ocr_class_knn.
