Eliminate Noise in Color Image Using method of Color Vector
应用颜色矢量法抑制彩色图象中的噪声干扰

It is more difficult to eliminate noise in color image than in gray image. In this paper, a method of color vector is described. Using this method, the noise in color image, which is made up of many monochromatic targets, can be restrained. Firstly, color vector is defined, and then the average of color vector is also defined. Secondly, a new analytical method of color vector is introduced. By calculating Euclidean distance between pixel, of which is analyzed, and averages of color vector of trained district, it is possible to segment rapidly the different monochromatic targets, which have been polluted. Thirdly, the images of monochromatic targets are smoothed separately. Finally, by combining the images of monochromatic targets that are processed and one of background, it is can eliminate noise in the color image greatly. The results of the method show that it is satisfy. The method is applicable to eliminate noise in image, which is made up of many monochromatic targets and complex background.
