Perception estimation of noising distortion in color components

Many kinds of methods are used to denoising every type of noising. However in this paper we find that even the same kind of noising has different perception of image quality distortion in each color component. In order to know the perception distortion of noising in color components, several simple discrepancy measurements are calculated for each channel of different color space, such as Euclidean Distance, Manhatton Distance etc. The most popular image quality estimation, PSNR, is also computed as a reference. Quality scores gained form different methods of each channel are analysed and compared. After that we can see the sensitivity of each color components to color image noising distortion.
