oBox filter Gaussian convolutionA fast low-accuracy approximation of Gaussian convolution
oDCT-based Gaussian convolutionConvolution via multiplication in the DCT domain
oDeriche Gaussian convolutionAn accurate recursive filter approximation, computed out-of-place
oExtended box filter Gaussian convolutionAn improvement of box filtering with continuous selection of sigma
oFIR Gaussian convolutionApproximation by finite impulse response filtering
oStacked integral images Gaussian convolutionA sum of box filter responses, rather than a cascade
\Vliet-Young-Verbeek Gaussian convolutionAn accurate recursive filter approximation, computed in-place
