描述
deserialize_ocr_class_knndeserialize_ocr_class_knnDeserializeOcrClassKnnDeserializeOcrClassKnnDeserializeOcrClassKnndeserialize_ocr_class_knn 用于反序列化一个基于 k-NN 的 OCR 分类器，该分类器此前已由 serialize_ocr_class_knnserialize_ocr_class_knnSerializeOcrClassKnnSerializeOcrClassKnnSerializeOcrClassKnnserialize_ocr_class_knn 进行序列化（有关序列化基本原理的介绍，请参阅
fwrite_serialized_itemfwrite_serialized_itemFwriteSerializedItemFwriteSerializedItemFwriteSerializedItemfwrite_serialized_item）。序列化的 OCR 分类器由句柄 SerializedItemHandleSerializedItemHandleSerializedItemHandleSerializedItemHandleserializedItemHandleserialized_item_handle 定义。反序列化的值将存储在一个自动创建的 OCR 分类器中，其句柄为 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。
