描述
deserialize_fft_optimization_datadeserialize_fft_optimization_dataDeserializeFftOptimizationDataDeserializeFftOptimizationDataDeserializeFftOptimizationDatadeserialize_fft_optimization_data 用于反序列化由 serialize_fft_optimization_dataserialize_fft_optimization_dataSerializeFftOptimizationDataSerializeFftOptimizationDataSerializeFftOptimizationDataserialize_fft_optimization_data 序列化的数据，以优化 FFT 的运行时性能（有关序列化基本原理的介绍，请参阅 fwrite_serialized_itemfwrite_serialized_itemFwriteSerializedItemFwriteSerializedItemFwriteSerializedItemfwrite_serialized_item
。该序列化数据由句柄 SerializedItemHandleSerializedItemHandleSerializedItemHandleSerializedItemHandleserializedItemHandleserialized_item_handle 定义。该优化数据必须已通过
optimize_fft_speedoptimize_fft_speedOptimizeFftSpeedOptimizeFftSpeedOptimizeFftSpeedoptimize_fft_speed 预先确定，并使用
serialize_fft_optimization_dataserialize_fft_optimization_dataSerializeFftOptimizationDataSerializeFftOptimizationDataSerializeFftOptimizationDataserialize_fft_optimization_data 进行序列化。如果序列化数据是针对应用程序中将要使用的图像尺寸确定的，则无需调用

optimize_fft_speedoptimize_fft_speedOptimizeFftSpeedOptimizeFftSpeedOptimizeFftSpeedoptimize_fft_speed 确定其值的同一台机器上使用。否则，运行时间将无法达到最优。另请注意，使用标准 HALCON 生成的优化数据无法在并行 HALCON 中使用，反之亦然。

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。
