Separation Technique Of The Color Map Theory And Practice

Color separation of true color map images is always the important content of color image manipulation, and the kernel technology of the map mode recognition and information acquirement. It is a matter of great significance for the quickly color map separation and print, especially with the development of the color desk to print technology and model recognition in recent years, the research works of this field is made active day by day.In order to solve the problem of quick color-separation of true color map images, the paper studied and discussed the basic principle of chroma, color models and their conversions , the theory and technology of the digital Image processing deeply. The theories and algorithms of color separation are compared earnestly and summarized systemically; The factors bring into chromatic aberration and affect the result of the color separations are studied. Some new methods of color separation are explored and innovated, a feasible plan was did. We can use the method based on the color-speciality of the color map image and image spatial relativity to get the result we want. At last, the paper summarizes all the works above and point out some views to be studied in the future.
