Imagick::reduceNoiseImage — Smooths the contours of an image
Esta função tornou-se DEFASADA a partir da Imagick 3.4.4. O uso desta função é fortemente desencorajado.
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.
