WebIn image processing, a Gaussian blur (also known as Gaussian smoothing) is the result of blurring an image by a Gaussian function (named after mathematician and scientist Carl Friedrich Gauss).. It is a widely used effect in graphics software, typically to reduce image noise and reduce detail. The visual effect of this blurring technique is a smooth blur … WebThis method is Non-Local Means Denoising. It takes more time compared to blurring techniques we saw earlier, but its result is very good.
