Detailed Description

template<typename T = SeFloat, class TPadding = PaddedImage<T, Reflect101Coordinates>>
struct SourceXtractor::DFTConvolution< T, TPadding >::ConvolutionContext

This strategy has the concept of a "context": things that can be precomputed only once and reused afterwards. This is useful, for instance, when the image is convolved multiple times with the same kernel (i.e. ModelFitting)
