Gaussian Blur

Applies a Gaussian blur effect on a static noise.

The principle of the Gaussian blur is to compute a new value for each pixel of an image, using the average value of the surrounding pixels weighted according to a Gaussian distribution. It means that the closer the surrounding pixels are from the processed pixel, the higher is their weight in the computation of the new pixel value. The window of surrounding pixels, used to compute the mean value, is named the kernel. The kernel size is the size of this window.

Gaussian blur gives better results than the box blur, but it is slightly more computationally expensive.
