描述
deserialize_ocr_class_knndeserialize_ocr_class_knnDeserializeOcrClassKnnDeserializeOcrClassKnnDeserializeOcrClassKnndeserialize_ocr_class_knn deserializes a k-NN-based OCR
classifier, that was serialized by serialize_ocr_class_knnserialize_ocr_class_knnSerializeOcrClassKnnSerializeOcrClassKnnSerializeOcrClassKnnserialize_ocr_class_knn (see
fwrite_serialized_itemfwrite_serialized_itemFwriteSerializedItemFwriteSerializedItemFwriteSerializedItemfwrite_serialized_item for an introduction of the basic principle
of serialization). The serialized OCR classifier is defined by the handle
SerializedItemHandleSerializedItemHandleSerializedItemHandleSerializedItemHandleserializedItemHandleserialized_item_handle. The deserialized values are stored in an
automatically created OCR classifier with the handle OCRHandleOCRHandleOCRHandleOCRHandleOCRHandleocrhandle。
执行信息
- 多线程类型：可重入（与非独占算子并行运行）。
- 多线程作用域：全局（可从任何线程调用）。
- 未采用并行化处理。
