serialize_ocrT_serialize_ocrSerializeOcrSerializeOcrserialize_ocr — Serialize an OCR classifier.

Warning

serialize_ocrserialize_ocrSerializeOcrSerializeOcrserialize_ocr is obsolete and is only provided for reasons of backward compatibility. New applications should use the MLP, SVM or CNN based operators instead.

Signature

Herror T_serialize_ocr(const Htuple OcrHandle, Htuple* SerializedItemHandle)

void SerializeOcr(const HTuple& OcrHandle, HTuple* SerializedItemHandle)

def serialize_ocr(ocr_handle: HHandle) -> HHandle

Description

serialize_ocrserialize_ocrSerializeOcrSerializeOcrserialize_ocr serializes an OCR classifier (see fwrite_serialized_itemfwrite_serialized_itemFwriteSerializedItemFwriteSerializedItemfwrite_serialized_item for an introduction of the basic principle of serialization). The same data that is written in a file by write_ocrwrite_ocrWriteOcrWriteOcrwrite_ocr is converted to a serialized item. The OCR classifier is defined by the handle OcrHandleOcrHandleOcrHandleocrHandleocr_handle. The serialized OCR classifier is returned by the handle SerializedItemHandleSerializedItemHandleSerializedItemHandleserializedItemHandleserialized_item_handle and can be deserialized by deserialize_ocrdeserialize_ocrDeserializeOcrDeserializeOcrdeserialize_ocr.

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

OcrHandleOcrHandleOcrHandleocrHandleocr_handle (input_control)  ocr_box → HOCRBox, HTupleHHandleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)

ID of the OCR classifier.

SerializedItemHandleSerializedItemHandleSerializedItemHandleserializedItemHandleserialized_item_handle (output_control)  serialized_item → HSerializedItem, HTupleHHandleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)

Handle of the serialized item.

Result

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