Name

write_ocr_class_knnT_write_ocr_class_knnWriteOcrClassKnnWriteOcrClassKnnwrite_ocr_class_knn — Write a k-NN classifier for an OCR task to a file.

Signature

write_ocr_class_knn( : : OCRHandle, FileName : )

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'".onc"".onc"".onc"".onc"".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.

Execution Information

Multithreading type: reentrant (runs in parallel with non-exclusive operators).
Multithreading scope: global (may be called from any thread).
Processed without parallelization.

Parameters

OCRHandleOCRHandleOCRHandleOCRHandleOCRHandleocrhandle (input_control) ocr_knn → (handle)

Handle of the k-NN classifier for an OCR task.

FileNameFileNameFileNameFileNamefileNamefile_name (input_control) filename.write → (string)

File name.

File extension: .onc

Result

If the parameters are valid, the operator write_ocr_class_knnwrite_ocr_class_knnWriteOcrClassKnnWriteOcrClassKnnWriteOcrClassKnnwrite_ocr_class_knn returns the value TRUE. If necessary, an exception is raised.
