Gaussian Blur

Kernel

The width and height of the Gaussian Kernel. Must be a positive odd number. Here I limit the kernel size between 3 ~ 21 since large kernels are unlikely. Typically we set the same value for Kernel X and Kernel Y.

Kernel X

Kernel Y

Sigma

Standard deviation of the Gaussian Kernel, each referring to the X and Y component. Set Sigma X to 0 to calculate from kernel size. Set Sigma Y to 0 (default) to make it the same value as Sigma X.

Sigma X

Sigma Y

Border Type

The type of padding to use on border. Check out the documentation for further information on each border type. The default value is BORDER_DEFAULT.
