template<class T_or_RGB> Image<T_or_RGB> transformDoG (  const SpaceVariantTransform &  sv, const Image< T_or_RGB > &  input, const int  surround_ratio = 2, const bool  center_on = true )

compute cortical scale space, subsample and return a space variant image with center surround structure. Be aware that types <byte> or PixRGB<byte> will be truncated > 0, losing the negative component. Cast to int or float first. Definition at line 194 of file CorticalTransform.C.
