Imagick::reduceNoiseImage — Smooths the contours of an image
This function has been DEPRECATED as of Imagick 3.4.4. Relying on this function is highly discouraged.
Smooths the contours of an image while still preserving edge information. The algorithm works by replacing each pixel with its neighbor closest in value. A neighbor is defined by radius. Use a radius of 0 and Imagick::reduceNoiseImage() selects a suitable radius for you.
