An image processing system includes an a noise detection unit that extracts a local statistical characteristic of a predicted original image according to a local statistical characteristic of an observed image and a local statistical characteristic of a predicted noise image, sets a flag level indicating a distortion state for each of pixels of the observed image according to the local statistical characteristic of the predicted original image, zones the observed image through a filter window, determines distortion states of adjacent pixels, corrects the flag level, and detects noise, and a noise removal unit that adaptively sets a filter size according to the corrected flag level and removes the noise, when the corrected flag level is determined through the noise detection unit, and therefore it is possible to implement adaptive noise detection and removal techniques of a distorted image damaged by noise, and detect a contour to the corresponding pixels into undistorted pixels. |
