STOIK Noise Autofix v.1.6 implements the latest automatic noise reduction algorithm developed by STOIK Imaging. The program cleans noise in photos from different sources

including digital cameras, cameraphones, and scanners. The main internal modules of the program are noise detector, noise analyzer and noise suppression filter.

Noise detector finds noise and distinguishes it from natural image textures and fine details. It is based on statistical Bayesian classifier. It was pre-trained on most typical noise

types and it can be trained additionally to take into account new specific noise patterns.
Noise analyzer measures noise parameters, builds the noise profiles, and decides what filter parameters are optimal for the particular noise type according to the proprietary image

quality criteria.
The noise removal filter processes the image to reduce noise level providing balance between preserving image details and noise suppression. The filtering is performed using a

multi – resolution image representation. During filtration the filter makes statistically optimal decision whether image element belongs to noise or not. Once the decision is made it

applies different methods to process noise and image elements. This software also includes automatic Smart Sharpening filter as an optional post–processing tool.
