## 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.

### Syntax

### Standards information
