How is Box Blur different from Gaussian Blur?

Question

Adobe Photoshop

When should you use Box Blur?

Answer 1

It is believed that box blur is a simplified version of gaussian blur. Accordingly, box blur is faster, but the result of the blur looks "square". Try taking any contrasting photo and applying the box blur filter, and then compare the result with the work of the gaussian blur filter on the same photo. Gaussian blur will give a smoother result, so this filter is usually used if you need to blur something. And, although box blur is faster, you will not see a difference in speed in photo editing. The difference in speed will only be felt when working on images with a resolution of about 60 MP or more. Although I took a picture with a resolution of 10000x6000 pixels. (60 MP), and the difference in blur between gaussian and box blur was literally 3 seconds (in the settings I set the blur radius to 600 pixels. ) That is, in image editing, you can, in principle, forget about box blur. It can be used in practice, for example, in motion design, in order to quickly get a rough version of blurring something on a large number of frames (here you can already save a lot of time).

Answer 2

Gaussian blurring is a technique similar to box blurring but uses a normal distribution to accomplish it's goal.

The difference is in the type of distribution - the Gaussian has a normal one, the ordinary one - I don't know which one.
