serialize_ocr_class_knnT_serialize_ocr_class_knnSerializeOcrClassKnnSerializeOcrClassKnn (Operator)

Name

serialize_ocr_class_knnT_serialize_ocr_class_knnSerializeOcrClassKnnSerializeOcrClassKnn — Serialize a k-NN-based OCR classifier.

Signature

serialize_ocr_class_knn( : : OCRHandle : SerializedItemHandle)

Description

serialize_ocr_class_knnserialize_ocr_class_knnSerializeOcrClassKnnSerializeOcrClassKnnSerializeOcrClassKnn serializes a k-NN-based OCR classifier (see fwrite_serialized_itemfwrite_serialized_itemFwriteSerializedItemFwriteSerializedItemFwriteSerializedItem for an introduction of the basic principle of serialization). The same data that is written in a file by write_ocr_class_knnwrite_ocr_class_knnWriteOcrClassKnnWriteOcrClassKnnWriteOcrClassKnn is converted to a serialized item. The OCR classifier is defined by the handle OCRHandleOCRHandleOCRHandleOCRHandleOCRHandle. The serialized OCR classifier is returned by the handle SerializedItemHandleSerializedItemHandleSerializedItemHandleSerializedItemHandleserializedItemHandle and can be deserialized by deserialize_ocr_class_knndeserialize_ocr_class_knnDeserializeOcrClassKnnDeserializeOcrClassKnnDeserializeOcrClassKnn.

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

OCRHandleOCRHandleOCRHandleOCRHandleOCRHandle (input_control) ocr_knn → (handle)

Handle of the OCR classifier.

SerializedItemHandleSerializedItemHandleSerializedItemHandleSerializedItemHandleserializedItemHandle (output_control) serialized_item → (handle)

Handle of the serialized item.

Result

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