About this App

This Gaussian operator is one of the main noise reduction techniques in image analysis and has many applications. This blur tool demonstrates how the Gaussian filter works and lets you experiment with it on your own images.

How to use the Gauss App?

The Gaussian blur demo works in a web browser without installing or downloading. The software is easy to use and you only need to use a few clicks to apply a blur effect to the whole image or parts of it.
