only.Expand description
This function constructs a Gaussian kernel parameterized by alpha
and stores the output in
kernel
. The parameter order
specifies the derivative order, with 0
corresponding to a
Gaussian, 1
corresponding to a first derivative Gaussian, and so on. If normalize
is set to
true
, then the kernel will be normalized to sum to one on output. If normalize
is set to
false
, no normalization is performed.
