描述

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。

执行信息

• 多线程类型：可重入（与非独占算子并行运行）。
• 多线程作用域：全局（可从任何线程调用）。
• 未采用并行化处理。
