deserialize_ocr_class_knnT_deserialize_ocr_class_knnDeserializeOcrClassKnnDeserializeOcrClassKnn (Operator)

Name

deserialize_ocr_class_knnT_deserialize_ocr_class_knnDeserializeOcrClassKnnDeserializeOcrClassKnn — Deserialize a serialized k-NN-based OCR classifier.

Signature

deserialize_ocr_class_knn( : : SerializedItemHandle : OCRHandle)

Description

deserialize_ocr_class_knndeserialize_ocr_class_knnDeserializeOcrClassKnnDeserializeOcrClassKnnDeserializeOcrClassKnn deserializes a k-NN-based OCR classifier, that was serialized by serialize_ocr_class_knnserialize_ocr_class_knnSerializeOcrClassKnnSerializeOcrClassKnnSerializeOcrClassKnn (see fwrite_serialized_itemfwrite_serialized_itemFwriteSerializedItemFwriteSerializedItemFwriteSerializedItem for an introduction of the basic principle of serialization). The serialized OCR classifier is defined by the handle SerializedItemHandleSerializedItemHandleSerializedItemHandleSerializedItemHandleserializedItemHandle. The deserialized values are stored in an automatically created OCR classifier with the handle OCRHandleOCRHandleOCRHandleOCRHandleOCRHandle.

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

SerializedItemHandleSerializedItemHandleSerializedItemHandleSerializedItemHandleserializedItemHandle (input_control) serialized_item → (handle)

Handle of the serialized item.

OCRHandleOCRHandleOCRHandleOCRHandleOCRHandle (output_control) ocr_knn → (handle)

Handle of the OCR classifier.

Result

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