Description

serialize_ocr_class_knnSerializeOcrClassKnn serializes a k-NN-based OCR classifier (see fwrite_serialized_itemFwriteSerializedItem for an introduction of the basic principle of serialization). The same data that is written in a file by write_ocr_class_knnWriteOcrClassKnn is converted to a serialized item. The OCR classifier is defined by the handle OCRHandleOCRHandleocrhandle. The serialized OCR classifier is returned by the handle SerializedItemHandleserializedItemHandleserialized_item_handle and can be deserialized by deserialize_ocr_class_knnDeserializeOcrClassKnn.

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 OCR classifier.

SerializedItemHandleserializedItemHandleserialized_item_handle (output_control) serialized_item → (handle)HTuple (HHandle)HSerializedItem, HTuple (IntPtr)HHandleHtuple (handle)

Handle of the serialized item.

Result

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