In this paper the method of converting image presented in shades of gray, in color, by solving the problem of color-coding. The results of comparative studies of semi-automatic method of color-coding and color-coding method based on spectral transformation. Based on a set of test images shows the results of the solution of the color-coding of different methods of color-coding. Comparative characteristics restore the color channels in the RGB color space is based on processing a set of test images, which show the benefits of using the color-coding method based on color markings. The use of this approach allows us to solve a wide range of tasks color restoration with limited a priori data. The results of the method of color-coding on the basis of the color-coded in the solution of changing the color of the image and objectives of the individual coloring of the image. The study of effective use of color-coding on the basis of the evaluation of the standard deviation between the original and evaluated the histogram color channel, the peak signal / noise ratio, the maximum absolute difference between the original and priced color channels. The results show high efficiency of the method of color-coding on the basis of labeling as compared to automatic methods.
