How do you do Gaussian blurring?

Go to Filter > Blur > Gaussian Blur, and the Gaussian Blur window will appear. You can drag the image in the Gaussian Blur window to look for the object you are going to blur. If you find it too small, tick the Preview box, and the result of the Gaussian Filter blur will be visible in the image.

How is Gaussian blur calculated?

To put it simply, the Gaussian blur algorithm is a process of performing a weighted average operation on the entire image. The value of each pixel is obtained by weighted averaging of itself and other pixel values in the field.

What is a 2d Gaussian filter?

Brief Description. The Gaussian smoothing operator is a 2-D convolution operator that is used to `blur' images and remove detail and noise. In this sense it is similar to the mean filter, but it uses a different kernel that represents the shape of a Gaussian (`bell-shaped') hump.

What is a good kernel size for Gaussian blur?

Typically, however, it's uncommon to use a kernel size larger than around 50 or so as things are usually already pretty blurry by that point. The Gaussian blur is a great example of simple mathematics put to a powerful use in image processing.
