描述

deserialize_fft_optimization_datadeserialize_fft_optimization_dataDeserializeFftOptimizationDataDeserializeFftOptimizationDataDeserializeFftOptimizationDatadeserialize_fft_optimization_data deserializes data, that was serialized by serialize_fft_optimization_dataserialize_fft_optimization_dataSerializeFftOptimizationDataSerializeFftOptimizationDataSerializeFftOptimizationDataserialize_fft_optimization_data, for optimizing the runtime of the FFT (see fwrite_serialized_itemfwrite_serialized_itemFwriteSerializedItemFwriteSerializedItemFwriteSerializedItemfwrite_serialized_item for an introduction of the basic principle of serialization). The serialized data is defined by the handle SerializedItemHandleSerializedItemHandleSerializedItemHandleSerializedItemHandleserializedItemHandleserialized_item_handle. The optimization data must have been determined previously with optimize_fft_speedoptimize_fft_speedOptimizeFftSpeedOptimizeFftSpeedOptimizeFftSpeedoptimize_fft_speed and must have been serialized with serialize_fft_optimization_dataserialize_fft_optimization_dataSerializeFftOptimizationDataSerializeFftOptimizationDataSerializeFftOptimizationDataserialize_fft_optimization_data。If the serialized data has been determined for the image sizes to be used in the application, calling optimize_fft_speedoptimize_fft_speedOptimizeFftSpeedOptimizeFftSpeedOptimizeFftSpeedoptimize_fft_speed is unnecessary. Note that the data should only be used on the same machine on which they were determined with optimize_fft_speedoptimize_fft_speedOptimizeFftSpeedOptimizeFftSpeedOptimizeFftSpeedoptimize_fft_speed。Otherwise, the runtimes will not be optimal. Also note that optimization data that were created with Standard HALCON cannot be used with Parallel HALCON and vice versa.
