#define  PCL_FFT_CONVOLUTION_IS_FASTER_THAN_NONSEPARABLE_FILTER_SIZE 12 
Defines a filter size in pixels above which FFTbased convolution is consistently faster than nonseparable convolution on the current PixInsight/PCL platform. More...  
#define  PCL_FFT_CONVOLUTION_IS_FASTER_THAN_SEPARABLE_FILTER_SIZE 162 
Defines a filter size in pixels above which FFTbased convolution is consistently faster than separable convolution on the current PixInsight/PCL platform. More...  
#define PCL_FFT_CONVOLUTION_IS_FASTER_THAN_NONSEPARABLE_FILTER_SIZE 12 
This value has been determined experimentally, and has been optimized for parallel execution on relatively fast machines with eight or more logical processor cores. Note that separable convolution is always faster than nonseparable convolution, so this value should only be considered for convolution with nonseparable filters.
