Notes
Remarks
The Gaussian blur kernel is an approximation of the normalized convolution
G(x,y) = H(x)I(y),
where
H(x) = exp(-x^{2}/ (2s^{2})) / sqrt(2* pi*s^{2})
and
I(y) = exp(-y^{2}/ (2t^{2})) / sqrt(2* pi*t^{2})
with 's' being the standard deviation in the x direction and 't' being the standard deviation in the y direction, as specified by the stdDeviationX and stdDeviationY properties.
