A Comparison of Noise Cleaning Techniques for Color Images

Abstract : An earlier report compared a number of iterative local noise cleaning techniques as applied to grayscale images. The present report provides some additional discussion of the grayscale results, and also applies several of the better methods to a color image of a house. Noise cleaning on each individual color component is compared with noise cleaning on the color vectors themselves. Results for two color coordinate systems, RGB and UVW, are also compared.
