描述

算子 close_ocrclose_ocrCloseOcrCloseOcrCloseOcrclose_ocr deallocates the memory of the classifier having the number OcrHandleOcrHandleOcrHandleOcrHandleocrHandleocr_handle. Hereby all corresponding data will be deleted. However, if necessary, they can be saved in advance using the operator write_ocrwrite_ocrWriteOcrWriteOcrWriteOcrwrite_ocr。The number OcrHandleOcrHandleOcrHandleOcrHandleocrHandleocr_handle will be invalid after the call; but later the system can use it again for new classifiers.

注意

All data of the classifier will be deleted in main memory (not on the hard disk).

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。

此算子修改后续输入参数的状态：

• OcrHandleOcrHandleOcrHandleOcrHandleocrHandleocr_handle

在执行此算子时，若该参数值需在多个线程间使用，则必须对其访问进行同步。

参数

HTuple      OcrHandle,Class,Confidence;
Hlong        orc_handle;

read_ocr("testnet",&orc_handle);
/* image processing */
create_tuple(&OcrHandle,1);
set_i(OcrHandle,orc_handle,0);
T_do_ocr_multi(Character,Image,OcrHandle,&Class,&Confidence);
close_ocr(orc_handle);

结果

If the parameter OcrHandleOcrHandleOcrHandleOcrHandleocrHandleocr_handle is valid, the operator close_ocrclose_ocrCloseOcrCloseOcrCloseOcrclose_ocr 返回值 2 ( H_MSG_TRUE )。否则将抛出异常。
