Short description🔗

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

Description🔗

write_ocr_class_knnWriteOcrClassKnn writes the k-NN classifier for an OCR task with the OCRHandleOCRHandleocrhandle to the file given by FileNamefileNamefile_name. If a file extension is not specified in FileNamefileNamefile_name the default extension '.onc' is appended to FileNamefileNamefile_name. write_ocr_class_knnWriteOcrClassKnn is typically called after the classifier has been trained with trainf_ocr_class_knnTrainfOcrClassKnn. The classifier can be read with read_ocr_class_knnReadOcrClassKnn.

Execution information🔗

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🔗

OCRHandleOCRHandleocrhandle (input_control) ocr_knn → (handle)HTuple (HHandle)HOCRKnn, HTuple (IntPtr)HHandleHtuple (handle)

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

FileNamefileNamefile_name (input_control) filename.write → (string)HTuple (HString)HTuple (string)strHtuple (char*)

File name.

File extension: .onc

Result🔗

If the parameters are valid, the operator write_ocr_class_knnWriteOcrClassKnn returns the value 2 (H_MSG_TRUE). If necessary, an exception is raised.
