AN APPARATUS FOR COLOR IMAGE DENOISING AND METHOD THEREOF

摘要

An apparatus for eliminating noise in a color image is provided. The apparatus includes a luminance image noise eliminator for applying a first filter to a luminance image of an input color image to generate a noise-removed luminance image, and a chrominance image of the input color image based on the noise- And a chrominance image noise canceller for generating a chrominance image from which noise has been removed. Thus, it is possible to achieve relatively low computational complexity while having high noise rejection performance at the existing non-local filter level.
