FIELD: information technology.
SUBSTANCE: filtration of noise from digital images is based on defining a local structure of the image and on non-local averaging in accordance with the defined structure. The local structure of the image is determined by successively rolling up predefined templates with neighbouring pixels and by selecting a RPC template which gives the least error after rolling up. Noise is filtered from the digital image through weighted averaging of pixel values in the search window.
EFFECT: fast filtration of noise in digital images which provides high quality of noise suppression without causing distortions.
