描述

The operator 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

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

This operator modifies the state of the following input parameter:

• OcrHandleOcrHandleOcrHandleOcrHandleocrHandleocr_handle

During execution of this operator, access to the value of this parameter must be synchronized if it is used across multiple threads.

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 returns the value 2 ( H_MSG_TRUE) . Otherwise an exception will be raised.
