Signature
Description
deserialize_fft_optimization_datadeserialize_fft_optimization_dataDeserializeFftOptimizationDataDeserializeFftOptimizationDatadeserialize_fft_optimization_data deserializes data, that
was serialized by serialize_fft_optimization_dataserialize_fft_optimization_dataSerializeFftOptimizationDataSerializeFftOptimizationDataserialize_fft_optimization_data, for
optimizing the runtime of the FFT (see fwrite_serialized_itemfwrite_serialized_itemFwriteSerializedItemFwriteSerializedItemfwrite_serialized_item
for an introduction of the basic principle of serialization). The
serialized data is defined by the handle SerializedItemHandleSerializedItemHandleSerializedItemHandleserializedItemHandleserialized_item_handle.
The optimization data must have been determined previously with
optimize_fft_speedoptimize_fft_speedOptimizeFftSpeedOptimizeFftSpeedoptimize_fft_speed and must have been serialized with
serialize_fft_optimization_dataserialize_fft_optimization_dataSerializeFftOptimizationDataSerializeFftOptimizationDataserialize_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_speedOptimizeFftSpeedOptimizeFftSpeedoptimize_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_speedOptimizeFftSpeedOptimizeFftSpeedoptimize_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.

Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
Parameters

Handle of the serialized item.
Result
deserialize_fft_optimization_datadeserialize_fft_optimization_dataDeserializeFftOptimizationDataDeserializeFftOptimizationDatadeserialize_fft_optimization_data returns 2 (
H_MSG_TRUE)
if all parameters
are correct. If necessary, an exception is raised.
