Gaussian Blurring

imago features a quick, one-click Gaussian blurring effect to remove image noise and details. Gaussian refers to the bell-shaped curve which smoothes out noisy images. A two-dimensional Gaussian filter is defined by its kernel size and standard deviation(s). imago uses a small kernel (2 pixels in radius) with a standard deviation 1.4.
