名称
deserialize_ocr_class_knnT_deserialize_ocr_class_knnDeserializeOcrClassKnnDeserializeOcrClassKnndeserialize_ocr_class_knn — Deserialize a serialized k-NN-based OCR classifier.
参数签名
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.
运行信息
- 多线程类型:可重入(与非独占操作符并行运行)。
- 多线程作用域:全局(可以从任何线程调用)。
- 未经并行化处理。
