Description

read_fft_optimization_dataread_fft_optimization_dataReadFftOptimizationDataReadFftOptimizationDataReadFftOptimizationData loads data for optimizing the runtime of the FFT from the file given by FileNameFileNameFileNameFileNamefileName. The optimization data must have been determined previously with optimize_fft_speedoptimize_fft_speedOptimizeFftSpeedOptimizeFftSpeedOptimizeFftSpeed and must have been stored with write_fft_optimization_datawrite_fft_optimization_dataWriteFftOptimizationDataWriteFftOptimizationDataWriteFftOptimizationData. If the stored data have been determined for the image sizes to be used in the application, a call to optimize_fft_speedoptimize_fft_speedOptimizeFftSpeedOptimizeFftSpeedOptimizeFftSpeed is unnecessary. It should be noted that the data should only be used on the same machine on which they were determined with optimize_fft_speedoptimize_fft_speedOptimizeFftSpeedOptimizeFftSpeedOptimizeFftSpeed. If this is not observed the runtimes will not be optimal. Furthermore, it should be noted that optimization data that were created with Standard HALCON cannot be used with Parallel HALCON and vice versa.
