Description

deserialize_ocr_class_knnDeserializeOcrClassKnn deserializes a k-NN-based OCR classifier, that was serialized by serialize_ocr_class_knnSerializeOcrClassKnn (see fwrite_serialized_itemFwriteSerializedItem for an introduction of the basic principle of serialization). The serialized OCR classifier is defined by the handle SerializedItemHandleserializedItemHandleserialized_item_handle. The deserialized values are stored in an automatically created OCR classifier with the handle OCRHandleOCRHandleocrhandle.

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

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

Handle of the serialized item.

OCRHandleOCRHandleocrhandle (output_control) ocr_knn → (handle)HTuple (HHandle)HOCRKnn, HTuple (IntPtr)HHandleHtuple (handle)

Handle of the OCR classifier.

Result

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